Here's a reading list for parallel programming in Haskell (via GHC) I've
collected while preparing a tutorial. Might be interesting to those
trying to get into multicore Haskell right now,

Your data type GridWidget doesn't have a parameter, yet you use it
like it has one.
data GridWidget = forall widget. (WidgetClass widget) => GridWidget

Hi,
I am trying out existential type, some sample code works well. Well,
my own code could not be compiled with message:
Grid.hs:45:11:
Kind error: `GridWidget' is applied to too many type arguments
In the type `GridWidget widget'
In the type `(GridWidget widget) -> (widget -> t) -> t

Vty is a terminal UI library. Release 4.0.0.1 brings a number of
important fixes,
features, and performance enhancements.
- Completely rewritten output backend.
- Efficient, "scanline rasterization" style output span generator. Has not been
fully optimized, but should be fast enough.
- Terminfo

Thanks a lot! Refactoring was indeed the 'killer app' in mind when
writing the exact-printer. For instance I don't expect it to be hard
to get HLint to apply suggestions automatically now, instead of just
suggestin
I'm somehow experimenting with GADT. I'm implementing FRP system and I
get such error:
Occurs check: cannot construct the infinite type: a = (a, b)
In the pattern: CircuitSplit f g
In the definition of `createChannel':
createChannel (CircuitSplit f g)
= l
Roundtrip is an important milestone for automated refactoring tools.
Nice work!

Based on the feedback from the meeting polls and the constraints of
our speaker, the September meeting has been scheduled for Wednesday,
September 16th from 7pm - 9pm. I've decided to move the meeting time

Actually they are _not_ limited to only the state monad, they just work
naturally there. There are a few functions that allow you to easily use them
outside a state monad (fetch, update, alter).
It looks like the haddock documentation is generated now. There are a couple

It might help to add -optc-m32 -opta-m32 -optl-m32 to /usr/bin/ghci,
too. (TH uses ghci)

Nice! I will definitely give it a whirl when I pick up my MUD again. I'm
currently using accessors there. I see your functions are limited to use
