I am very interested. I recently encountered a serious performance
regression from 7.8 to 7.10 which seems to be fixed in 8.0. Now it's
not clear whether this was a library change or ghc itself. I suspect
the latter but given the performance is better in 8.0, I was not
motivated to confirm this.

I am happy to wrap up my example in whatever format but note that it
does pull in quite a few libraries.
