Re: [Haskell-cafe] Pulling a monad out of a functor

http://haskell.org/ghc/dist/current/docs/libraries/base/Data-Traversable.htm...

pull is sequence, fmapM is mapM (also see the sequenceA, traverse functions for the more general case of applicative functors vs. monads)

Ah yes, thank you! Saying "It seems to me that if this were a class, the implementor would be defining a traversing order by defining pull" should have tipped me off to check out the 'Traversable' class before asking (but, having probably only seen that class once or twice before in passing, it was probably too deep in my head for quick retrieval).
