You are wrong. This is just syntactic sugar for ordinary function.
Only difference is that in case of named function no syntactic sugar
is involved. One particular thing on operator overloading is
name mangling that have to be done.
Allowing operator overloading, but not function overloading,
restricts name mangling only to operator functions, which is good.
