I would love to have foldl' as part of the Prelude. I use it quite frequently and it seems like a beginner trap to have foldl but not foldl' (which is almost always the better choice). I see that foldMap has been added (in addition to all of Monoid and Traversable), why was foldl' left out?
That is one way but I think another way is to make foldl strict: http://www.well-typed.com/blog/90/ I'm tired of explaining the difference of foldl and foldl' to beginners. :-) --Kazu
