traverseWithKey for Data.Map et. al.
by roconnor＠theorem.ca 03 Nov '13

03 Nov '13

Has there yet been a proposal for adding traverseWithKey :: Applicative f => (k -> a -> f b) -> Map k a -> f (Map k b) to Data.Map and friends yet? If not I'll draw up a proposal. -- Russell O'Connor <http://r6.ca/> ``All talk about `theft,''' the general counsel of the American Graphophone Company wrote, ``is the merest claptrap, for there exists no property in ideas musical, literary or artistic, except as defined by statute.''

Add laws to Alternative
by Nathan van Doorn 01 Nov '13

01 Nov '13

Proposal: add the following laws to the documentation of Control.Applicative.Alternative: - empty <*> a = empty - f <*> empty = empty These laws correspond to the laws given in MonadPlus- if you take mzero = empty and ap = (<*>), the ones in MonadPlus imply these- and I don't think this proposal should be too controversial.
