attached is a patch to fix a module name and generalise a couple functions in Data.Map to be usable in an arbitrary monad (rather than being restricted to Maybe). if someone could integrate it, that would be great. John -- John Meacham - ⑆repetae.net⑆john⑈

-lookup :: Ord k => k -> Map k a -> Maybe a +lookup :: (Monad m,Ord k) => k -> Map k a -> m a +lookup' :: Ord k => k -> Map k a -> Maybe a

How about providing lookup (as is or as your hidden lookup') and lookupM as generalization instead? Cheers Christian
