It seems like a good idea.

I believed that 'pack()' was equivalent to 'pack(4)'. Now I think it
may be in fact equivalent to 'pack(pop)'.
Also it seems you can do jumps in the stack using labels as is
described in the following page. Maybe winemaker should have support for
something like this.

I think this is beyond winemaker's scope. It would require parsing
the file, detecting that a macro is defined and then called with a
different number of arguments, then going back and changing the macro
definition...
It seems to complex, and thus too likely to fail, to me. Also it does
not seem to be something very common that would make it really
worthwhile. It's not like the case issues or the pack issues which occur
many times in many applications.
