I think this is a problem that we will encounter often; I've got into the
same problem with container versions of
standard algorithms. I think having two namespaces is
the second best idea. I think having two different names is an inferior
idea. The best would be to use an enable_if
mechanism to remove the ambiguity.

I haven't used the lately accepted lib, but how portable is it? If its
portable, it might be worth looking into.
