[Haskell-cafe] Haskell version of Norvig's Python Spelling Corrector

[Pete Kazmier]

Recently I read an interesting article by Peter Norvig[1] on how to
write a spelling corrector in 21-lines of Python.  I wanted to try and
implement it in Haskell.  My implementation is terribly slow and I was
hoping for some tips on how to improve it and make it idiomatic.

I'd love to see other Haskell implementations as well if anyone has a
few moments to spare.  Admittedly, it took me several hours to get my
version working, but I'm a Haskell newbie.  Unfortunately, I think it
runs as slow as it took me to write it!  There is definitely something
wrong with it, a memory leak, because I can't correct more than a few
words without a great deal of memory being consumed.

Thanks,
Pete
