Note: this patch does not add scanl' to Data.List, but only to GHC.List. I don't know that I have enough community support as yet to add it publicly, but I want it for Data.List.inits, and it seems sensible (to me) to put it next to scanl.
I don’t think there will be doubts about it. It has pretty obvious semantics, and it is clear that it’s nice to have it. If you make a proposal you will get affirmative silence and a +1 from me :-) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9368#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
