Comment (by dylan at dylex.net):

 More efficient versions of the related functions to find the values left
 or right of a key would be nice, too:
 {{{
 findMinBnd, findMaxBnd :: Ord k => k -> Map k v -> (k,v)
 findMinBnd low = findMin . snd . split low
 findMaxBnd high = findMax . fst . split high
 }}}
