Not to mention you have to overload operator<, operator!=,
operator==, operator>, operator<=, *and* operator>= in order to
get the right results in all cases.
In D, you have to overload opEquals and opCmp. Hmm, I wonder
why I enjoy programming in D more than C++...
Comparison is better in C++. This is a weak spot in D. You could
do the same in C++ as D if you wanted to. You can detect the
presence of operator< in overload templates, but being explicit
is not much work and more flexible. Just cut'n'paste the set you
want...
