This is a simple very good suggestion. Thanks!

This is something interesting (i.e., I'm not sure what the standard says ;)

As far as the instantiations for char and wchar_t are concerned, as an
implementor I'm allowed to peek, right?

As far as the instantiations for whatever != {char, wchar_t} are concerned,
is really a user of the library supposed to provide a less<>() consistent
with char_traits? Can you enlighten me about that?

Paolo.
