Here is my own opinion.
I don't see what is wrong with using member function of local classes
and being explicit about when a reference or a copy of local variable
is needed. I can see why one may have a crying need for it in C; in
C++, the expressive power it provides seems very much quite unnoticeable.

There were lots of new proposals this week, and when something akin to
nested functions/lambdas were mentioned, my impression was that they
weren't the features that would have support from the "main" players.
