Hi,
I'm struggling with text-0.1 and text-icu-0.1, as announced at
http://www.serpentine.com/blog/2009/02/27/finally-fast-unicode-support-for-haskell/
The code in
http://pastebin.com/m7d8d9f91
is intended to read in a UTF-8 file a1.txt, reverse it twice, and
write it out to another UTF-8 file
http://pastebin.com/m88c7dc
It works fine if you delete the .Lazy.
Enjoy, and thanks...

This works fine without the .Lazy, and is also fine under
Another newbie question, but I can't seem to find any answers on the web...

readdirAll :: PD.DirStream - IO [String]
readdirAll d =
do dir - PD.readDirStream d
if dir ==
then return []

Sorry for the bandwidth

Hello,
Can someone elucidate to me this behaviour from ghci 6.6.1? Why is the
