Macro for detecting single argument, removing prefix - Misiur - 15.02.2015

I almost managed to detect 0, 1, or multiple arguments:

pawn Код:

#define Foo(%0) @d:@c:@a:@b:Bar(%0)
#define @c:@a:@b:Bar() No arguments
#define @a:@b:Bar(%0,%1) More than one argument
#define @b:Bar(%0) Single argument

Foo(Hai)
Foo(Hai, Hello)
Foo(Hai, Hello, Dickbutt)
Foo()

pawn Код:

#pragma ctrlchar 0x5c
#pragma pack false
#pragma semicolon true
#pragma tabsize 8
#file test.pwn
#line 5

@d:@c:@a:Single argument
@d:@c:More than one argument
@d:@c:More than one argument
@d:No arguments

Now, I completely have no idea how to remove leftover detector tags, as @d macro is already defined. Is there a clear way to do this? With some second compiler pass dark magic?

Or you could just use, you know, numargs()? Where are you heading with this?

Of course, but I'm simply curious.
