Regular streams are destructive. I was talking about "functional"
ones. I didn't try them myself, but the manual says one can perform
left recursion with them (thanks to their non destructive nature).
Mind the pattern matching, though: it is quite different from the one
used with regular streams.

the syntax looks like:

let f s = match s with fparser (* and not just 'parser' *)
...

If I remember well.
