Hi Haskell,
I have a question about the Haskell FFI and creating FunPtrs to
Haskell functions.
Does anyone have any recommendations for when I have a top-level

Now, what we can do with kl1? We can feed it an integer, say 1, and
obtain function f of the type s - (s,Bool) for an _unknown_ type s.
Informally, that type is different from any concrete type. We can
never find the Bool result produced by that function since we can
never have any concrete
I would like to conditionally expose a number of internal modules in a
library depending on a cabal flag - the idea is that new features
could be implemented externally to the library without contaminating
the source with undesirable changes. However, I've been unable to
find a way to structure a

One problem to consider - a downstream user of the new features won't
know that they need to pass special flags to your module, and may not
even know that they are using your module if the dependency is a few
steps
Hi, I came up with the following extremely compact version of Gaussian
elimination for matrices represented as functions. I searched the web
but found nothing resembling it, probably because of its inefficiency.
Has anybody seen something like it before?
Thanks

This is a linking issue. It seems GHC 7 automatically feeds the
linker SimpleJSON.o so when you explicitly provide it too then you get
those conflicts. All you need to do is call:
ghc -o simple Main.hs
Unless you're using GHC 6, then the original command is correct:

Hi all,
Does this trigger recollection in anyone:

Does there exist any sample code or other resources on writing a custom
SQL-to-Haskell datatype converter instance for use with HDBC that would be
accessible to someone just starting with Haskell? The reason I need this is
because of this problem (using PostgreSQL):
