// Recently I asked in clc++m about reasoning behind forbidding usage

As far as I can see technically it is possible to provide
implementation for Standard Library template components such that
would not require knowing complete type at the point of instantiation.
So it could be possible to modify The Standard in such a way that
instantiation of Standard Library template components would not cause
undefined behavior and be quite legitimate.

Am I wrong?
