Hi,
apparently the timing doesn't work properly in ghci 6.6 (at least for me), I
always get very small timings, usually 0.01 secs, sometimes 0.00 secs, once
0.07 secs, no matter how long it actually took.
Is that a common problem or is it only me?
Cheers,
Daniel

Although this doesn't answer your question, I think it is releated. When
implementing SHA, I need to create a recursive function to append the
length of a string to the string. This function needed to be strict,
because it needed to accumulted the length of the string, and it needed to

How was that with Haskell and Unicode???
While up to ghc-6.4.2 the following function worked it now doesn't compile:

I think this probably belongs on ghc-users rather than
Haskell.
Anyhow, there aren't any ASCII characters higher than 127.

Either convert your file to utf-8 encoding or read
http://www.haskell.org/ghc/docs/6.6/html/users_guide/release-6-6.html
GHC now treats source files as UTF-8 (ASCII is a strict subset of UTF-8,
so ASCII source files will continue to work as before). However, invalid
UTF-8 sequences are ignored

I've been writing some code that relies heavily on the type system.
Some of my polymorphic functions end up too polymorphic.
I'm looking for some tips and references regarding prescribing
poly-/mono-morphism. I know of three ways to do it:
1) rely on the monomorphism-restriction -- kind of scary
I'm wondering about creating a data structure that has the type of
decreasing numbers. If I want an increasing list, it is easy...
{-# OPTIONS -fglasgow-exts #-}
data Succ a = S a deriving Show
data Zero = Z deriving Show
data Seq' a = Cons' a (Seq' (Succ a)) | Nil' deriving
Here's an attempt with GADTs:
\begin{code}
{-# OPTIONS_GHC -fglasgow-exts #-}
data Succ a
data Zero
data Seq a b where
Cons :: a - Seq a b - Seq a (Succ b)
Nil :: Seq a Zero
\end{code}
Seems to work for me.

Good, writeCSV writes out every row immediately after it got it. I
eliminated (++ [nl]) in the hope of reducing the constant factor
slightly. Using difference lists for that is nicer but here you go.
I'm not sure how you'd use difference lists here.
Also, for some reason GHC runs
