After defining these for the umpeenth time, I would like to add the functions takeRec, genericTakeRec and spanRec to Data.List, as per http://hackage.haskell.org/trac/ghc/ticket/3671

I have also defined your "takeRec" a number of times in the past, but I have called it something like "splitAts".
I've been using it for years, under the name "groupsOf" - which is also consistent with Data.List naming conventions, and a bit less confusing than "splitAts" in my opinion. Another reason I don't use splitAts is that I don't use splitAt in its definition anymore; I've come to prefer groupsOf n = takeWhile (not . null) . map (take n) . iterate (drop n) In fact, I use this function so much that I put it in my dot-ghci so it will always be at my fingertips. I am very much in favor of adding it to Data.List. Regards, Yitz
