Data.MonoTraversable.Unprefixed

The functions in Data.MonoTraversable are all prefixed with the letter o to avoid conflicts with their polymorphic counterparts. This module exports the same identifiers without the prefix, for all cases where the monomorphic variant loses no generality versus the polymorphic version. For example, olength is just as general as Data.Foldable.length, so we export length = length. By contrast, omap cannot fully subsume fmap or map, so we do not provide such an export.
