{-# LANGUAGE ImplicitParams, UnboxedTuples #-}
-- Test two slightly exotic things about type signatures
module ShouldCompile where
-- The for-all hoisting should hoist the
-- implicit parameter to give
-- r :: (?param::a) => a

r = error "urk"
-- The unboxed tuple is OK because it is
-- used on the right hand end of an arrow
