How to use blank prefix parameters inside macros?
Code:
macro foo prefix {
        call    prefix#func
}

func:   ret
x_func: ret

foo x_
foo     ;<-- assembles to "callfunc" and gives error

Sorry to reply to myself.

I am currently getting around the problem like this:
Code:
macro foo prefix {
    match x,prefix#func \{
        call    x
    \}
}

func:   ret
x_func: ret

foo x_
foo    
But I am not happy about how it looks with the extra match in there.

Does anyone have another, clearer, way around this problem? Or am I just plain stupid and missing something obvious?

try this one, use conditional assembling.

Code:
macro foo prefix {
        if prefix eq
          call func
        else
          call  prefix#func
        end if
} 

func:   ret
x_func: ret

foo x_
foo

Thanks for the suggestion. It still looks untidy, but I think that is a little bit clearer than the match.
