Inlining the single method of a class can shadow rules

This shows up in template-haskell, module Language.Haskell.TH.Syntax, where the single method of the Lift class:

class Lift t where
  lift :: t -> Q Exp

has a RULE:

{-# RULES "TH:liftString" lift = \s -> return (LitE (StringL s)) #-}

There is currently no way of preventing lift from being inlined.
