name:                   dlist-nonempty
version:                0.1.1
x-revision:             3
synopsis:               Non-empty difference lists
description:
  Difference lists are a list-like type supporting O(1) append. This is
  particularly useful for efficient logging and pretty printing (e.g. with the
  Writer monad), where list append quickly becomes too expensive.
  .
  > DList a         ≅ [a] -> [a]
  > NonEmptyDList a ≅ [a] -> NonEmpty a
  .
  For empty variant, @DList@, see <http://hackage.haskell.org/package/dlist dlist package>.
