I've mentioned it a couple of times now, so I'll stop after this one, but I sent the original email because I had spent a few hours tracking down such an example. When I went through and cleared out all the uses of [..] I found a few other sketchy uses that may have been as yet unmanifested bugs. Actually, it was due to the additive nature and increasing inaccuracy, so if the suggestion is to just to filter <= on the last element than that's not a big improvement from my point of view. But anyway I promise you Enum Double wasn't what I really wanted. I wrote my own range function that is what I really wanted. And my guess was that it's actually want most people really want. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
