In the GHC document, section "GHC-specific concurrency issues", it says:
In a standalone GHC program, only the main thread is required to
terminate in order for the process to terminate.
I have a program (which does some fairly complex things with forking processes,
calling sockets etcetera)

Hi,
I'm trying to set up some socket connections with Haskell on a Windows 2000
platform, but I can't seem to get them working.
My program is rather simple:
--
import Socket
main = do { socket - listenOn (PortNumber 1234)
; return ()
}
--
I know this shouldn't do
You need to init WinSock first, i.e.,
main = withSocketsDo $ do {...}

Hi all,
For years I have wondered why the Num class has the Eq class
and the Show class as super classes.
Because of this, I cannot make functions an instance of Num
(becuase they are not in Eq or Show). Or a datatype
respresenting an infinite amount of digits (because Eq would
not make any
Is there a common way to pronounce "=" in discussions or when teaching?
I've learned all my Haskell from printed/visual documents.

How about 'bind'? and "" = 'then'.

memory usage climbs to 1.6M with ghc and needs -K20M, whereas with
main = print ([1..102400] :: [Integer])
memory usage is only 1300 bytes.
