I've been using deepseq quite a bit lately, but for the purpose of debugging space leaks. If, when I deepseq a big structure, the space leak goes away, I can then apply it to some subset. After much trial-and-error I can find something which is insufficiently strict. Ideally I can then strictify that one thing and stop using the deepseq. I wish there was a more efficient way to do this. I also use it to explicitly force certain parts of a data structure so they evaluate in parallel, though that part is not actually done yet. _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
