Description:
FoldMap lists; profiling libraries
FoldMap lists are lists represented by their foldMap function. FoldMap lists have O(1) cons, snoc and append, just like DLists, but other operations might have favorable performance characteristics as well. These wild claims are still completely unverified though. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
