i can take this work. although i personally thinks that this library more needs internal than external changes and interfaces are close to fine
Since I'm not a Haskell expert, I'm of the opposite mind: the internal stuff seems fine to me (the joy of ignorance), but the external face is rather confusing. The number of Wiki pages and mailing list discussions dedicated to the peculiarities of the libraries suggest that others were confused, too. [Newbies are always confused, so this isn't a bullet-proof argument.] I think that simply reviewing and revising library function names while deprecating the old ones woudl provide much improvement in return for little breakage. In any case, if you would (1) start the process or (2) recommend how we start this process up, I'd be more than happy to contribute ideas/suggestion/sweat, whatever the result. - Alson
