http://darcs.net is the screened repo. I've just fixed this bug, by
reverting to using C(r u r) as it should be.

bsrkaditya: the C(...) macro hides the type-variables when witnesses are
disabled; since it's a macro, once GHC sees the code, the macro's been
expanded as shown in fx's output...

This appears to only be a problem with older GHC (I'm using 7.0.4 and
have no warnings/errors).
