equivT :: Ord n => Type n -> Type n -> BoolSource
Check equivalence of types.
Checks equivalence up to alpha-renaming, as well as crushing of effects and trimming of closures.
- Return
False
if we find any free variables. - We assume the types are well-kinded, so that the type annotations on bound variables match the binders. If this is not the case then you get an indeterminate result.
equivWithBindsT :: Ord n => [Bind n] -> [Bind n] -> Type n -> Type n -> BoolSource
Like equivT
but take the initial stacks of type binders.
equivTyCon :: Eq n => TyCon n -> TyCon n -> BoolSource
Check if two TyCons
are equivalent.
We need to handle TyConBound
specially incase it's kind isn't attached,
