in modeling real application we have often the case that the type of
some object depends on a value. e.g. small_boat is a vessel with size
less than a constant. big_boat is a vessel with a larger size. for
example, many legal classifications are expressed in this form (e.g. car
vs. truck)
Fellow Haskelleers,
I'm pleased to announce the release of haskell-src-exts-1.9.0!
* On hackage: http://hackage.haskell.org/package/haskell-src-exts
* Via cabal: cabal install haskell-src-exts
* Darcs repo: http://code.haskell.org/haskell-src-exts
1.8.2 -- 1.9.0
===
* OptionPragma
[Apologies for multiple copies.]

Hi!
I finish writing my proposal (maybe a bit too late).
I would be glad to read any feedback.
Hi Diego,
Generally a good proposal. It would be great for Cabal's Simple build

* Build reporting in the hackage server
The idea here is that cabal sends back anonymous reports to the
server to say if a package compiled or not, and against what
versions of dependencies. This would make it clearer to
maintainers if their dependency
To actually build the examples, I also needed to remove references to the
addCondPropagation optimization pass. I don't know why. I attached the darcs

As a footnote: I doubt I will be the only one is confused because
cc-options get passed to c2hs but cpp-options don't. Perhaps the
cabal designers should revisit this choice.
I mostly agree.

Only cabal-install does this, plain Cabal only takes flags that were set
by the user.
No, plain Cabal does it

Excerpts from Daniel Fischer's message of Sun Apr 11 16:20:30 -0400 2010:
I think in the default cabal config, build-reporting would be turned off
and you'd have to turn it on yourself. Turning it on by default wouldn't be
sensible.
I doubt you'd get very much runtime with that. I'd suggest
