Whew, this is _not_ an argument for being practical in my view.
Are you implying that a programmer who wants to use Ada.Containers,
whether he/she is familiar with the STL or not,
should see to it that both ISO/IEC 8652:2007(E) (Ada)
and ISO/IEC 14882:2003 (C++) and associated documents
are available for reference?

Yes, and the RM should stay helpful, too. If I wanted to use shared
variables in a C++ program, and be asked to consult the Ada programming
language and protected types, will this suggestion be acceptable
to any practical C++ programmer? No.
