Huh? Operator overloads in FPC don't use "var" at all. Either you have a 
unary operator like "not", "inc" or ":=" then you have one parameter and 
one result or you have a binary operator like "+", "and", ">=" then you 
have two parameters and one result.

If an operator has an inline modifier then its code will be inlined if 
nothing (from the compiler's perspective) speaks against it (overloaded 
operators are simply converted to function calls).
