Welcome to the club :-)

http://www.mail-archive.com/glasgow-haskell-users@haskell.org/msg06012.h tml I tried Simon's version, but it throws a "Fail: Ix{Int}.index: Index (5) out of range ((0,4))" error. Haven't tracked down the cause yet.

So I guess that the upshot is just that "GHC is slow on this test." Is lazy evaluation what is slowing this down so badly?

There's no fundamental problem here. We just need decent support for packed strings and hash tables (or tries?) of them. Cheers, Simon
