Just reporting a silly message that appears after uninstalling GHC in
Windows98 (perhaps other windows platforms also):
don't forget to add [ghc path]/bin to your PATH
Why would it be necessary, since I am uninstalling it?
Cheers,

Thanks for the report. I'm not 100% certain why it happens in 5.04.2,
but it doesn't happen in the HEAD. The error message is still not
great, but at least it's not gibberish.

The desugarer generates tuples when desugaring mutually-recursive
functions, and I bet that is what is causing the problem.
These optimiser usually gets rid of them, as you found.
It's a known shortcoming which has never gotten high enough up the list
to solve.
Could you please keep the source
