Not yet.
I'll get round to it once I'm done with with an Agda presentation I'm
working on. Until then I can't afford to break my environment.

The GLUT-backend calls system.exit when the window is closed, because
'exitMainLoop' is only defined within freeglut, which is not by default
installed on non-linux platforms.
There is hence no real point in running gloss applications with the
GLUT-backend from GHCi.
I'll try to find a

Such a thing is certainly nice to have.

How is it possible to run 2 different versions of GHC
if you installed the binary packages in standard locations,
look in /usr/local/bin/ghc* : you have ghc-6.12.3, ghc-7.6.1 etc.
and each one knows how to find their libraries.
you can even say cabal install --with-ghc=ghc-7.6.1 foo
I would expect this to work, maybe with some additional notation (a la
ScopedTypeVariables)
{-# LANGUAGE FunctionalDependencies #-}
{-# LANGUAGE MultiParamTypeClasses #-}
class Foo a b | a - b
class Foo a b = Bar a where
foo :: a - b - c
The type family equivalent works
I'd like to announce ticketimer.com -- it's a website
that is not done yet. With ticketimer you can
choose films for your local cinema. People can buy
tickets in advance and promote the films they like.
Do we need to eat this blockbuster stuff all the time?

I'm new to concurrent programming in Haskell. I'm looking for a
drop-in replacement for 'mapM' to parallelize a set of independent IO
operations. I hoped 'mapConcurrently' might be it, but I need
something that will only spawn as many threads as I have CPUs
available [1].
I also tried
Is there a tool available that will tell me if the cabal file for my
library or application has any unnecessary build-depends?
I have a habit of developing new modules within an application and then
moving them out to separate libraries. For instance, I might move module
Foo out of my application

Cool, that's the library I'm looking for! I see it uses
'numCapabilities' to get the command-line value for '-N' and not
'getNumCapabilities' to query the system for how many cores are
available. So using the 'Local' module, this works:
