I've got a project coming up that I could use haskell for, providing I can convince myself that it's appropriate. The critical question is:
Anyone using Haskell in a long-running production application? I'm talking about something where the program would run for weeks or months non-stop, with either multiple threads or multiple copies.
I have a rather stupid application that parses feeds from the Twitter API. For each username given on the command line, it calls forkIO and the new thread enters a recursive loop: recurse x y z = do ... recurse x y z forever and ever. Contrary to my expectations (I still basically don't know what I'm doing in Haskell) it seems to run in constant space for months at a time.
