I agree that overloaded operators can be nice.  However, they also can
be easily abused.  A popular one is to use + for string concatenation
"'cause it's just like you're adding the two strings together."  Well,
you aren't adding them you are concatenating them.  If "ab" + "cd" is
"abcd" then 123 + 456 must =be123456, right?  :-)

And as for complex numbers, if you have a good compiler that allows any
type to be returned as a function result then:

a := Complex.Add(b,c);

is much clearer than your example (though in this case still not as nice
as a:=b+c).
