Description

This module implements permutation parsers. The algorithm used is fairly complex since we push the type system to its limits :-) The algorithm is described in:

Parsing Permutation Phrases, by Arthur Baars, Andres Loh and Doaitse Swierstra. Published as a functional pearl at the Haskell Workshop 2001.

data PermParser tok st a

permute :: PermParser tok st a -> GenParser tok st a

(<||>) :: PermParser tok st (a -> b) -> GenParser tok st a -> PermParser tok st b
