The case in your original message is particularly annoying, but at least
it only affects ghci. I thought it had been fixed, but it is still
present in 6.4.1, so perhaps it's waiting for 6.5?

I generally find that most of GHC's errors are real, ie they don't
change much when I fix earlier errors. (It seems to report only one
error per function to achieve that?) It's fun to work through the dozen
reported mistakes, then compile again to see how many I actually fixed.
