I think that is time for a standard library revision. And I ask: Why in
each new version the older parts don't evolve?

C++ thankfully does not follow the boneheaded doctrine that everything must
be an object, like whatever language you wish C++ was instead, so class Main
is not going to happen.
*"And I ask: Why in each new version the older parts don't evolve?"*
There's a thing called backwards compatibility, which although you clearly
don't care about - many, many other users do, as do the Committee. I'd've
thought that had been explained when you made such suggestions before
*.*
Having said that, there are ideas about a new stdlib floating around, and
I'm sure changes to iostreams are among them. Have you investigated those?

It might be interesting if you explained in what way the verbose code
suggested in that example would be better than what exists, if only to
orient debate towards the ideas you are trying to convey.
I doubt most C++ programmers would see this kind of code as an improvement
over the current situation. I know I don't, but maybe I don't understand
what you have in mind.

Please answer the question; if there's no problem you can identify clearly,
then this might not be the right forum for you. It's Ok, there are many
other discussion spaces out there.

They do evolve. What they do not do is:
1: Radically change themselves with every version of the language.
Backwards compatibility is not something we break lightly. Or pretty much
at all without fair warning.
2: Use different naming conventions because a guy on a forum prefers
InterCaps to under_scores.
If you would like to put forth a coherent proposal for some aspect of the
standard library to change, feel free. But all you've done in this thread
is make vague claims about the standard library not evolving in the
direction you prefer. That's hardly constructive.
Before you do so however, you might want to consider that it's unlikely
that people will find "change the naming convention of everything to
Java-style" to be a useful starting point.

That *really* depends on who you ask. And what code you're talking about.
And what the purpose of that code is.
Error codes are a perfectly valid means of communicating failure
conditions. So are exceptions. Each is appropriate in its own domain. But
we should never believe that one is so superior to the other that the other
never ought to be used.
Personally, I'm in favor of always giving the user a choice about such
things.

Why is StringList not const? That's the real question here.
Also, what is StringList? Never seen that in C++ before.
Wouldn't it be std::forward_list<std::string>?
Or maybe forward_list<string>?
Hell, I'd settle for even list<string>; why have a hard coded type for
StringList when you could have a generic type that can be used over and
over, like our current std::list?
It also looks like you are iterating over the StringList to get each string
as an item; sure.
But why do you then need to pass the length of the item (a string) to cout?
Why can't cout interpolate with a string enough to know the "length"
automatically?
What happens when string is passed to a different kind of out? Does it need
to pass the length every time?
Why don't we have an idiom to make this easier and reduce effort?
Seems like the current C++11 standard is better in this regard:
int main(int argc, char* argv[]) {
std::vector<std::string> arguments(argv, argv + argc);
for(auto&& item : arguments) {
std::cout << item << '\n';
}
}
Look, mine is even smaller!

... and jftr, in C++11 you can just do that by accepting an 'error lambda'
in your function:
template<typename OnError>
int parseInt(const std::string& s, OnError error)
{
int ret = 0;
for (char c : s) {
if (!is_digit(c)) return error(ret);
ret *= 10; ret += c;
}
return ret;
}
int main()
{
std::string s("123a");
std::cout << parseInt(s, [](int) { throw ParseException(); } );
std::cout << parseInt(s, [](int i) { return i; } );
std::cout << parseInt(s, [](int i) { return -1; } );
}
Thanks,
-lorro

Bjarme says us to use the std:: massively, but we can't do it.

What are you talking about? Why is it "obsolete"? Who is "Bjarme" and why
can we not '"use the std:: massively"? As Patrice said, you haven't
actually described a problem or introduced a solution, so there is no
proposal here, and so this is the wrong place to publish your half-formed
opinions and have irrelevant back-and-forth quips with other users. Start a
blog or something.

"Obsolete" means it's outdated to the point of being risky to use. That
does not describe the stdlib. You not personally liking its naming
conventions, or a lack of uniformity among them, does not make it
"obsolete".
I also fail to find anywhere that you have described how it the stdlib is
not "robust", by any usual definition of that word. I think the programmers
who maintain the various implementations of the stdlib would appreciate
being informed if somehow their products are not robust, really. Again,
lack of uniformity or propensity for verbosity do not make something
non-robust.
Even if this weren't all just based on your opinions, you are not providing
any actual thesis for why and how it should be changed. A series of
expositions on things you don't like and very vague riddles posed to other
users do not constitute a proposal.

As I said, I'm not talking naming convetins; The std:: is obsolete, what
is < c++11 is
untouched. I think in a std:: like the Qt library: Each part works fine
with alll stuffs, Each part supports any other, It doesn't have incomplete
classes, types, modules..., and so on. It the Qt library Guidline be
applied to std::, It won't be robust.
P.S.:
Qt guidlines, but with:
exceptions,
size_t for indexing strings, streams, ...)
without moc.
[And again, I'm not talking about naming conventions.]

Jos=C3=A9,
I find your train of thought very difficult to fathom. I might not be
bright enough to understand what you are trying to convey.
I will suggest, once again, that if you want to submit a proposal here, you
take the time to write it throroughly, explain your proposal, ensure it's
clear enough to people you normally read in English, and only then post it.
Remember that there are other locations to express yourself if you don't
like something for personal reasons and want to vent. This forum is not
such a place.

Neither, as argv isn't const; the contents of that array may be modified by
the program.
Not sure what that has to do with your contrived example though, and it
doesn't answer literally any of the other questions I asked.

"Work" in what sense?
Yes, you can use any output fstream, even one opened with `ios::binary`,
with that code. It will do exactly what it says it does: write the
characters of a string with no text-to-binary translation, followed by a
`\n` character with no text-to-binary translation.
Does that satisfy your definition of "work"? Or are you trying to serialize
objects, which is a very different, and *far* more complex, operation?

fstream is a kind of stream, sure. But we are dealing with cout. Which is
not an fstream, but an ostream.
