Today yet another newbie in #haskell asked about a 'split' function for lists, and I got fed up with saying 'no one can agree on the right interface so it doesn't exist, just write it yourself', because it's a really dumb answer, even if it's true. Instead of trying to get a 'split' function added to Data.List (which will never ever happen), I thought, why not create a module Data.List.Split which contains implementations of every conceivable way to split a list? Of course, people will probably still argue over what should go in such a module, what to name the various functions, etc., but hopefully we can converge on something useful. I've created a Data.List.Split page on the wiki: http://haskell.org/haskellwiki/Data.List.Split Please add code to it! Once something useful is hashed out we can upload it to hackage. Perhaps eventually some of it can be folded into the standard libraries, but this seems like a much more lightweight way to get started. -Brent
