Clear as water. Maybe you could include this explanation on the docs, 
so people like me (new to operator overloading) doesn't ask again.

As I'm working on a pascal wrapper for a C++ API, I wanted to "emulate" 
as close as possible the C++ classes. And as some of those classes have 
some operators overloaded, I wanted to do the same on pascal. Of 
course, C++ operators where overloaded _inside_ of those classes.

Well, I'll have to wait for an "operator TMyClass.= (a, b : TMyClass) : 
Boolean;" :-)

Thanks.
