I think this is better handled by a library solution - define standard 
templated comparators somewhere and have special support for these.  There 
are dozens of ways to write the same comparison in D and allowing equality 
tests to work in some cases is likely to be as frustrating as string1 == 
string2 working sometimes in java.
