ReadP would be much more useful if it had some introductory Haddock documentation too, including a reference to Koen Claessen's paper, if you felt up to doing that too.
And here I was, completly unaware space and time efficient monadic parsers were even possible! :) Any chance a couple of changes could be made to ReadP 1. let the type of tokens be an argument 2. give Fail a String argument and have it preserve the string passed to 'fail'. I don't think either will adversly affect performance, yet will make it possible to use ReadP as a simple standard (as in comes with the libraries) very lightweight parsing monad without compromising its main goal of implementing a faster Read.
