I have to admit that I am beginning to like Mark's solution with the numbered subfilter definitions, even though I unfairly called it "not really pretty". The neat thing about it is that adding another level of "pseudo-recursion" is very easy and very clear. Putting everything into a single filter is complicated to maintain with all sub-expressions having different length (different number of tagging[] constructs). Here, everything looks the same, with just some numbers changed. I think I'm gonna implement this!
