I argue if you want to sequence_ a map you should write mapM_:
mapM_ putStrLn [line1, line2, line3]
Nice
mapM is under-appreciated? More under-appreciated are line

From ghc-6.4, the runtime system no longer flushes open files; it
truncates them instead. You should close (or flush) the file explicitly
with 'hClose' or 'hFlush' before the program terminates.
I added 'hClose' to processXmlWith in the Wrapper module. That solved the
problem.
Thank you!
It's not supported on i386 platform yet :(

Hi,
DP will support the i386 build as soon as Wolfgang makes his
changes available. As I understand, from earlier messages on one
of the ghc* lists, this is almost done for the pre-6.6 branch, but not
yet backported to the 6.4.x branch.
Also, DP uses a binary bootstrap compiler to build ghc,

Thanks to some advise by one of the other posters i have chosen to try and set up a list that uses lookup to find the values of the elements within it.
However what i have attempted so far has resulted in odd answers or errors. Anyway here it is, i have given each element a string at

Hi All,
I really appreciate all the help I received when I asked you to
critique my PrefixMap module a few weeks ago. I think I am making
good progress in correcting the lisp in my Haskell programming.
I'll be very grateful to anyone who can take a glance at the attached

Haskell gurus,
We have made a proposal to extend the Erlang `binary' data type from
being a sequence of bytes (a byte stream) to being a sequence of bits (a
bitstream) with the ability to do pattern matching at the bit level.
This proposal has now been fully implemented all
these at the level

One thing I noticed, is that you are measuring IO in the Haskell
version of drop3. hGetContents is lazy.
