First of all, you can write usual TCP server in Haskell and use it from
Erlang. It would be handy to use some widely used protocol, like
Memcached or Redis.
If in some reason you want to use Foreign.Erlang, make sure that you are
using the same cookie and the same node name type (short or

On Tue,
Magiclouds asked how to build values of data types with many
components from a list of components. For example, suppose we have
data D3 = D3 Int Int Int deriving Show
v3 = [1::Int,2,3]
How can we build the value D3 1 2 3 using the list v3 as the source
for D3's fields? We can't
This seems like a bug in GHC. But it has nothing to do with MVars. I've
narrowed this down and filed a bug report here:

Hi Brandon,
indeed in my example if you add:
*b - evaluate a*
after the definition of a it works.
However, in my original program it doesn't work, I suppose because I
interpret the user submitted code (here *let (a::String) = a *
for the example) via Hint and Hint-server, and the interpretation
Great, with me compiled with ghc -threaded the bug shows up.
However, runnning main in ghci doesn't show the bug (it finishes
correctly).
I have GHC 7.4.1.

Hi MagicCloud,
A worse, but perhaps simpler alternative to Oleg's solution uses Data.Dynamic:
import Data.Dynamic
data LongDec a = LongDec a a a a a a a a
deriving (Show, Typeable)
values = abcdefgh
mkLongDec :: forall a.
I'm not sure that there is anything great about this bug. It seems to me
to be a rather severe demonstration of a somewhat already known design flaw
in the runtime :(
Could you please comment on the actual bug rather than replying here so that
the devs see that this behaviour has been

I think you need something wha Scala has - the ability to create a partial

Hi,
AFAIK it is (partially?) fixed in HEAD, see

It works for me with -fno-omit-yields

Say I have things like:

values = [ 'a', 'b', 'c', ... 'x', 'y', 'z' ]
Now I want them to be LongDef 'a' 'b' 'c' ... 'x' 'y' 'z'.
In form, this is something like folding. But since the type changes, so
