Comment:

 >  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 :-)
