Proposal: Move some functions from Control.Monad to Data.List

[Edward Kmett]

I'd be a lot more keen on this proposal if it was suggesting just to *also*
export them from Data.List, rather than move them. A lot of code imports
them from their existing location, and this doesn't provide a clean upgrade
path for users.
