in the sense that 'x' is recursively applied to the output of 'x'.
i have no idea what you would mean by applying the same 'x'
expression to the output of said 'x' expression, as regular expressions
are greedy and can't count.  wouldn't they all loop forever?

can you outline somehow what you're thinking of?
