This is definitely a potential problem, but I note that you can also get into this mess without OO in any language that lets you put a (reference to) function in a variable. Or, god help you, operator overloading.
If I overload shift-left `<<` for a completely different concept such as "piping", that's my mistake. That's like writing a normal function or method and calling it `foo()` when it has nothing to do with the concept of fooing.
That said, unless you are writing a math library or some container, there's not many good uses for operator overloading.
Yours and C++'s.
Maybe a good analogous method would be an overloaded `.ToString()` in C# that has side effects or returns the full text of the Magna Carta or something.
The particular problem is that search engines tend to have terrible support for searching for arbitrary sequences of non-alphabetic characters.
