Proposal: Add strict versions of foldlWithKey and insertLookupWithKey to Data.Map
+1, insertLookupWithKey' I could have used recently. Is there some reason why all the other WithKey functions don't require strict variants? Asked another way, suppose I want to build a Map via foldl' (unionWith (+)) without space leaks, is that possible?
