Comment(by simonpj):
Thanks for this. I see what is happening -- it is a palpable bug.
To fix it I have changed the `HsType` data type a bit. But that's part of
the GHC library API, and we aren't supposed to change the API in a patch-
release (ie in 6.12.2). So we have two alternatives
* Fix it in the HEAD, but not 6.12
* Fix it in 6.12, but thereby change the 6.12 API a bit
Any opinions? Can you use the HEAD?
The default is the first alternative.
Simon
