The compiler can not detect such collisions, because it stops searching 
for a symbol if it found a suitable one. This also explains why you need 
the "overload" directives in certain cases of cross unit overloading 
(because then the compiler will search for more). This is one of the 
reasons why the compiler can compile code so fast: It does not need to 
check all loaded units of a unit (and there are units that contain many 

So from me this gets a definit -1 in big letters.
