This is a bug release that fixes a bug spotted by Srihari Ramanathan
where the Dot representation of Color values were double-quoted when
they shouldn't have been.

Hi, I was trying to use the solution given, but I don't know how to use it...
How do I create something that is of type List?
data List a = Nil | Cons a (List a)
>From the previous examples, I was thinking something like Cons 'a' 'b' 'c'
would create a list ['a','b','c'] but it gave me errors...

Hello,
I think that Even refers to an example like this:
module A where
data A = A { a :: Int }
The following works:
{-# LANGUAGE NamedFieldPuns #-}
module B where
import A
f (A { a }) = a
However, if we import "A" qualified, then punning does not seem to work:

That's the implication, but I can't seem to trigger the case short of
[re]moving the .leksah directory and redoing the config that way...

A brief black-box view of it shows that it opens and closes

BTW, it works better when I don't give it a directory with numerous
branches of Xen and the Linux kernel - somewhat unfortunate that this
causes massive memory use. Now to figure out how to get it to
properly configure/build projects!

Hey Guys!
I was writing a small implementation of the earliest-end-first algorithm
for the Interval Scheduling problem just now. When I was done, I thought
it would be a nice thing to have a QuickCheck property for my code. This
is what I came up with:
-- Intervals are just triplets
type Interval

Why does it need more than 3GB of RAM at this point (I have 4GB and
see 70% going to Leksah before I kill it)? I didn't point it at
_that_ much Haskell code to parse though. Does it read everything
into some bloated internal format before parsing?

Oh, good to know. I had no idea you could use cmd.exe to run cabal and darcs
and that it would work.

Great! Just a little note: MSYS isn't required to install Darcs with
cabal on Windows, just to develop or run tests.
