Why the sudden change in versioning scheme (from 0.x to 1.x)?

Welcome to issue 246 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of September 23 to September 23, 2012.

Hi,
Just a heads up: on Ubuntu 12.04 with GHC 7.4.1 out of apt (no
haskell-platform,) using the bootstrap.sh script fails, because the
constraints for CABAL_VER_REGEXP are too lax:
$ sh ./bootstrap.sh
Checking installed packages for ghc-7.4.1...
Cabal is already installed and the version is ok.

I've pushed a fix for this. We'll wait a couple days to give a chance
for other issues to be discovered, and then Johan will make

Exactly. I should have been more explicit but that's what I meant about
"adding another module". You would import Control.M

I wondered whether there is a brilliant typing technique that makes
Data.Map.! a total function. That is, is it possible to give (!) a type,
such that m!k expects a proof that the key k is actually present in the
dictionary m? How can I provide the proof that k is in m?

Hey,
I have debian 6.0.5 with GHC version 6.12.1 and base version
4.2.0.0 (although base 3.0.3.2 is also installed).
Hope that helps!

Hello,
I just tried to upgrade cabal-install using an older version and it
yields the following error:
Distribution/Client/JobControl.hs:63:6: Not in scope: `mask'
If you need any machine/software specs let me know.

On the behalf of the many contributors to cabal, I'm proud to present
cabal-install-1.16.0. This release contains almost a year worth of
patches. Highlights include:
* Parallel installs (cabal install -j)
* Several improvements to the dependency solver.
* Lots of bugfixes
We're also simultaneo
I'm not sure that exposing a liftIO for Monad.Par is the best idea. Since
all these parallel computations use runPar :: Par a -> a, it advertises
that the result is deterministic. I'm not really comfortable with a hidden
unsafePerformIO hiding in the background.
That said, I don't see a reason for
Several of the monad-par schedulers COULD provide a MonadIO instance and
thus "liftIO", which would make them easy to use for this kind of parallel
IO business:
http://hackage.haskell.org/packages/archive/monad-par/0.3/doc/html/Control-Monad-Par-Scheds-Direct.html
And that would be a little more
I see. There exists an equivalent version but more generic?
Just out of curiosity, I'm still pretty new to arrows, as you may have read
:)
Thanks,

Thanks Brent, this should do the trick, although what I was asking was
something more general:
For "explicitly pass" I meant passing them without the eta reduce, in other
terms:
swapA' :: (Arrow a) => a ((b,c), (b,c)) (c,b)
swapA' t = () swapFirst >>> swapSecond (???)
where
swapFirst

Hello everyone,
sorry for the dumb question but I'm wrapping my head around arrow just from
this morning.
Consider this toy function to swap argument of a tuple:
swapA' :: (Arrow a) => a ((b,c), (b,c)) (c,b)
swapA' = swapFirst >>> swapSecond
where
swapFirst = first $ arr snd
swapSecond
No, that's not the problem. I want to parse with more complicated asts
containing both Text and antiquotes.
