G'day all.
Quoting "Alexandru D. Salcianu"
I'm interested in more than one Set implementation, one FiniteMap implementation etc. (we already have this in the standard Haskell'98 library).
The closest thing we have to this in semi-active development is Edison. Current version is here: http://sourceforge.net/projects/hfl/ It may not have all of the association/collection implementations that you want, but if you're already resigned to implementing them, then making them Edison-conformant wouldn't hurt. :-) Let me know if you want checkin rights.
Furthermore, I'm interested in a library that can be compiled / interpreted by a mainstream tool, e.g., ghc, hugs etc. I've already started writting such a library (mainly for didactic purposes), but I would like to know if an enstablished collection library already exists.
Edison works fine under GHC. It hasn't been officially ported to Hugs, but it doesn't use any GHC-onlyisms. I believe that hierarchical libraries, multi-parameter type classes and fundeps are the only extensions used. On the topic of Edison, everyone seems to agree that it's a good idea, but nobody seems to want it as an official part of their distributions, and for a good reason: It doesn't _quite_ seem like The Right Thing(tm). This is one reason why further development hasn't been a high priority lately. Cheers, Andrew Bromage
