Capture avoiding substitution of witnesses in expressions.

If a binder would capture a variable then it is anonymized to deBruijn form.

- class SubstituteWX c where
- substituteWithWX :: forall a n. Ord n => Witness a n -> Sub n -> c a n -> c a n

- substituteWX :: (Ord n, SubstituteWX c) => Bind n -> Witness a n -> c a n -> c a n
- substituteWXs :: (Ord n, SubstituteWX c) => [(Bind n, Witness a n)] -> c a n -> c a n

class SubstituteWX c whereSource

substituteWithWX :: forall a n. Ord n => Witness a n -> Sub n -> c a n -> c a nSource

substituteWX :: (Ord n, SubstituteWX c) => Bind n -> Witness a n -> c a n -> c a nSource

Wrapper for `substituteWithWX`

that determines the set of free names in the
type being substituted, and starts with an empty binder stack.

substituteWXs :: (Ord n, SubstituteWX c) => [(Bind n, Witness a n)] -> c a n -> c a nSource

Wrapper for `substituteWithWX`

to substitute multiple things.
