--- If we miss any rules for Ids defined here, then we end up
--- giving the local decl a new Unique (because the in-scope-set is (hackily) the
--- same as the non-local-rule-id set, so the Id looks as if it's in scope
--- and hence should be cloned), and now the binding for the class method 
--- doesn't have the same Unique as the one in the Class and the tc-env
---	Example:	class Foo a where
---			  op :: a -> a
---			{-# RULES "op" op x = x #-}
--- 
--- NB we can't use isLocalId, because isLocalId isn't true of class methods.
