  When dipping my toes into C++ to do a quicksort algorithm, I 
quickly got annoyed I'd have to create all the individual 
comparison functions rather than just one like in D... Which is 
one thing I'm seeing from the converted 'toy'. Actually I ended 
up making an opCmp and then overloading all the individual types 
to use the opCmp.
