Depends on the application, of course. The (on by default) parallel GC
tends to kill performance for me... you might try running both with "+RTS
-sstderr" to see if GC time is significantly higher, and try adding "+RTS
-qg1" if it is.

I use ghc-mod for vim and it sorta supports this... by adding
arbitrary flags to GHC in your vimrc:

I'm porting lzma-enumerator over to conduits and I've run into a snag.
The output chunks from lzma can be quite large, so I'd like to stream
the results out in smaller chunks instead of tens (or hundreds) of
megabytes at a time. It seems as though this should be possible, as it
is with enumeratees,

We use waf to drive cabal. It supports parallel builds at the 'c

Is this different than the "--hide-successes" flag for test-framework? Looks
like it was added a few months back:

It was purely just for demonstration. I did update the code with a few more
comments, but the enumerator package may not be the easiest thing to grok.
You might try putting up your current code and someone might be able to
recommend a better or easier approach.

Perhaps something like this would work: https://gist.github.com/1096039
I didn't test to make sure it works, but you could probably hack toget
(/) operates on a Fractional instance... but length returns an Int, which is
not a Fractional.
You can convert the Int to a Fractional instance:
mean xs = sum xs / fromIntegral (length xs)
or try an integer division:
mean xs = sum xs `div` length xs

XCode 4 is for sale in the App Store for $5. You do need an account, but not
a developer account... so it may be a bit more palatable.

Waf supports parallel builds and works with GHC without too much trouble. I
use it in a mixed Haskell, C++, Scala and Python build. If there is interest
I could conceivably clean up the ghc waf tool and release it.
