Hi, This is either a GHC bug, or a Yhc+Hugs bug - I'm not sure which, but the compilers disagree: import Prelude hiding ((==)) data Foo = Foo instance Eq Foo where (==) a b = True GHC says: Temp.hs:14:4: `==' is not a (visible) method of class `Eq' Yhc and Hugs both successfully compile the module. Does anyone know which compiler(s) are in the wrong, and need bugs filing? Thanks Neil
