As Mark Blewett has mentioned in "Proposal: two real uses for the auto
keyword" thread,
elegant extension to scope or member access operator is desired.

Instead of annoying sequences like

  for(std::vector::iterator i= v.begin(); i!= v.end(); i++) {...}

more elegant, more simpler and inherently low-cohesion

 for(v.iterator i= v.begin();...
or
 for(v::iterator i= v.begin();...

is proposed.

It seems to be not very difficult (especially in v::iterator case).
Why not?

Could you be more specific ?
I can read your question in at least two ways -
Q) Why is it not very difficult ?
A) Because the compiler already knows the type of v
or
Q) Why is it not (yet) C++ ?
A) Because there are many forms possible. Another proposal was to
use typeof(), so the example can be written typeof(v)::iterator
As a C++ community, we don't know what is best.

IIRC, g++ already has __typeof(). Now if people favoring another
syntax would also add that to g++, we could compare the different
approaches.
