[snip]
I recently withdrew from this project and offered up the libs I'd been working on as they are for a new owner. Didn't get any takers though (no surprises there!). I've always found the lack of apparent interest in all this somewhat puzzling myself. It's not as if there's no latent demand for efficient collections. (Data.Map is probably the most regularly whined about of all the "standard" libs.)
FWIW, I find the same phenomenon with Edison. I get very little feedback about it positive or negative; I really have no idea how many people are using it. I guess people are more willing to roll their own data structures or use the standard libs. It might be from a desire to limit dependencies. If that's the case, perhaps continuing cabal developments will change that.
