I am not sure if a *standarized* container-like interface will have a good
impact on a program design.
The range interface is a *very* powerful abstraction, much much better than
the abstraction of an (encapsulated) container.
IMHO, the decision to shortcut from (c.begin(),c.end()) to (c) should be
done consciously, not as the default practice; otherwise, a program might
end up stuck in a design that cannot exploit the flexibility of the range
Of course, this is just my personal view.
I'd like to know what the STL designers have to say about this matters. Do
they monitor this forum?
