Um, except for string concatenation, which overloads '+' and '+=' in Java...
If you allow any overloading, you can always make bad choices.
For the most part, operator overloading in C++ either (a) fits the domain
at hand and makes code more readable and maintainable, or (b) is done
because you cannot define arbitrary syntaxes (such as various expression
template based libraries like Boost.Spirit and Boost.Lambda).
