Yes!
Well, not for me and you, but propably for most POV-Ray users. Remember,
that POV has a scripting language which is complicated enough for most
people already. You and I know about typecasts and functions etc. Don't
forget that even #macros are just that, and not fully fledged functions. And
in fact #declares are very similar to C/C++ #defines.
Anyway I don't see the big advantage of overloading. I don't see the
advantage of overcomplicating the script language either. Not everyone who
can use POV should be able to program.
