Prior to r1300 it was even easier: no change to Clojure was required. > Could'nt it be interesting to consider adding the possibility to make > self recursive calls inherent to lazy-seqs, as I proposed ? While having played a lot with rec-cons, rec-cat and rec-seq — which can prove useful in simplifying some code —, I'm still ambivalent about the general case of recursive data structures in functional programming that's why I'm not lobbying for their inclusion in core. > Have you looked at the patch I provided ? Yes: simple and clever.
