C++ emphatically does *not* support overloading on return type only.
That has a very simple reason: unlike Pascal, C++ does not force you to
assign the result of a method or function call to a variable, so it
cannot always tell what you're doing.
The same reason pretty much goes for perl: if I have array and hash
versions of a function, how can it tell which one to call if I don't
assign the results?
