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,
