Indeed. I am sorry.
60 lines above it is visible a typo of `where':
reordEPol :: EPPOTerm -> EPol a -> EPol a
reordEPol t (EPol ms _ pol) =
let { ecp = eppoECp t; cmp (_,p) (_,q) = ecp q p }
in
EPol (sortBy cmp ms) t pol where

It is interesting.
Maybe, it is a kind of GHC misfeature?
By the way, these 60 lines, they, probably, work as expected in the
