the language, touch a few interesting packages,
and show how to use GHC on Fedora. If anyone from the Haskell community is
going to Flock and has requests or suggestions for what I should talk
about, post a reply!

, if I'm right, this bug affects GHC and Hugs. But this code has
surely been around long enough that someone would have found this already?
But there's not a bug in hackage's trac system.
Help!

I'm not familiar with modal logic, but if modalities stack, you might be
able to do something like this.

{-# OPTIONS_GHC -fglasgow-exts #-}
module Test where
data L a
= F | T | Atom Int
| Neg (L a) | And (L a) (L a) | Or (L a) (L a)
| M (L
I run into the problem with test1 all the time: It's accumulating
partially evaluated expressions like this:
1+1+1+1+1+1+...
and filling up memory. Try foldl' instead, and look here:
http://en.wikibooks.org/wiki/Programming:Haskell_List_Processing
Also have a look at this past discussion:
I came up with a system of coloring -- you'll have to view this message as html to see it. You start with the input parameters -- those are green. Anything defined in terms of green is blue. Anything defined in terms of green blue is purple. Anything defined in terms of green, blue, and purple is
:ones
which is perfectly okay. The loop in the first example happens
because it starts to evaluate x, and determines that it has to know x
to do the evaluation, but the evalutation of x is already under way.
