Well, you could compute n from what you know but that would imply
creating a new regular expression for each iteration which is probably
not what you want.

I was actually thinking about a simpler version which was just a
zero-length thingy that you could insert anywhere in your code and
which would call a user-defined function. It'd be more efficient and I
think you could still achieve with it what you want.

I'll try to release something in the next days.

Cheers,
