From where I'm sitting, the main problems with Haskell packages are thus:
1. For certain tasks, there are multiple possible packages, and it's not
really clear which one to go for. Having more than one choice is good.
(E.g., there's Gtk2hs and there's wxHaskell, and you pick the one you
want based on personal preference.) Having *dozens* of different
packages for the same task, some more complete than others, some more
maintained than others, etc., is just confusing.
2. Most things on Hackage don't seem to want to work on Windows.
(Evidently this is being worked on. Stream Fusion installed just fine
with a little help from Duncan...)
3. It's not easy to tell from the package summary whether it does what
you want. (It looks like this too is being worked on with automatic
generation of Haddoc information, which should help. Assuming there's
any Haddoc comments to display, that is...)
4. General package quality. Some are excellent, some aren't. Given time,
hopefully the excellent ones will rise to the top, and the less good
ones will improve or dissappear. So it looks like this one is just a
question of time and effort. Hopefully this will also somewhat solve #1
Just my opinion - others are welcomed to dissagree. ;-)
