In that case, I would *strongly* suggest designing your macro to be 
extendable to begin with -- e.g. equip it with a helper macro that acts 
as hook. There might in rare cases be a need to pass parameters to this 
hook (although storing them in helper macros is typically easier), but 
there should never be a need to use delimited arguments.
