There are a number of scenarios, but I control > the initial definition, 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.
