Wow, I think now is time for me to also try to learn more the stuff that is in clojure-contrib ! Anyway, it was interesting to try doing it by tweaking clojure itself :-) Could'nt it be interesting to consider adding the possibility to make self recursive calls inherent to lazy-seqs, as I proposed ? It's a one line change in a clojure class, and a one line change in lazy-seq also. And I don't think it would have performance impacts for people not willing to use that. Have you looked at the patch I provided ?
