The identifier method has a good deal of possibility also, basically it (potentially) becomes an efficient iterating method like $*. As long as it was able to be nested within other identifiers it could be very useful. Note that there's nothing preventing for from being both a statement and an identifier.
oh yes, if it can be used inline to overcome the problems $* currently has, that would be really nice to see
i was thinking of it as related to $findfile() with its command parameter, but functionality like $* would make much more sense
