Hi, list!.
Now in 6.12.1 we have DeriveFunctor, DeriveFoldable and DeriveTraversable. This
greatly simplifies the reuse structure style of programming. Some structure
(not just _data_ structure) got captured in ADT and can be reused for various
purposes.
Wouldn't it be nice to have the

Hi, list.
This is a long post, sorry. The bottom line: specifying +RTS -Nn where n
number of cores slows the program compiled with 6.12.1 by orders of magnitude
under Mac OSX. Turning off parallel garbage collections with -qg
resolves the problem. Independent verification is appreciated.
Thanks, Simon.
I know I should try to find the existing ticket before posting :)

Did you really seen 100ms pauses?! I never did extensive research on this but
my numbers are rather in microseconds range (below 1ms). What causes such a
long garbage collection? Lots of allocated and long-living objects?

Is it possible to make GHC-7.0.1 to generate intrinsic instructions instead of
calls to C library to compute trigonometric functions?
main = do
a - readLn
print $ sin a
I tried -O -msse2 -fllvm and their combinations. Generating assembly always
contains calls for computation
For me only hackage.haskell.org works (resolves to 69.30.63.204),

As far as I remember GHC generates FPU instructions for sinus
Hi list (and hopefully Jefferson Heard!)
I'm trying to play with OpenCL Raw package. While it has a great amount of work
put into it it's not currently usable. Frankly, it does not even link (due to
foreign import typo).
It does not compile with GHC 7.0.1, has badly specified dependencies on

clever refactoring tool ready that can convert pure into monadic
functions and vice versa.
Not trying to attack the idea, just some thoughts:
I don't see much problem converting pure function into an effectfull
form :) Having pure function

Hi, list!
I have a file:
\begin{code}
module Main where
import MyModule
main=do
print hello
\end{code}
MyModule is in MyModule.lhs
when building with
ghc -o main -fhpc --make Main.lhs
I get perfectly working code, but MyModule.mix lacks any usable
coverage information:
Mix
No I do not process it using lhs2tex. I just compile literate haskell
code. The necessity of preprocessing kills the entire idea of having
literate source. I just feed lhs files to ghc and everything works
fine except code coverage.

Hi café !
I googled for some kind of vim support for cabal but found nothing. I
mean syntax highlighting of .cabal and probably integration with
haskellmode. Did anyone hear about such thing?

Great ! I'm just starting with Vim so I'm not sure if I could
contribute. But I definitely will look into the sources. Thanks!

Sorely, Haskell can't prove logic with it. No predicates on values, guarantee
that proof is not _|_. Haskell makes bug free software affordable, that's true.
But it's not a proof assistant.
