Two years ago I've been told by a professort that a+++a+++a depends on the
language and the compiler. Yesterday i found this page :
http://www.blueshoes.org/en/developer/syntax_exam/
If a=1 ->
Java : 6
PHP : 6
gcc 2.95  : 3

I know that is "on the edge" and I will never use it in real script by I was
curious why the
reference change the result.

Best wishes,
Andrey
