I don't understand your proposal. It seems to propose something that
already exists (It's a so-called function-try-block) and it shows code that
is not related to the title of the proposal but is currently not valid
("std::cerr.printf").

So what is the actual proposal?

Thanks,

- Daniel

First, don't post images when text will do a much better job. Second, stop
top-posting.

Third, what actual *problem* does it solve? And note that "I'd rather write
my code this way" is *not* a genuine problem. There is no power that this
feature would give you which you would be unable to have without it.

As far as I understand, this already exists in the language (and
coincidentally is the only way to capture exceptions thrown in a ctor init

Not quite. If you use function-level try blocks, the catch blocks are not=

considered part of the function itself. So they cannot `return`; they can=

only `throw`. For some reason, the OP wants to be able to return from them.=

Even though they are declare outside of the function.

The constraint of function-try-blocks that you describe here, relates

for the exception handling is already valid and allows to return
normally.
