Synopsis

class DeBruijn a where
- deBruijnVar :: Int -> a
- debruijnNamedVar :: String -> Int -> a
- deBruijnView :: a -> Maybe Int

Documentation

class DeBruijn a where Source #

Things we can substitute for a variable. Needs to be able to represent variables, e.g. for substituting under binders.

Minimal complete definition

deBruijnView

Methods

deBruijnVar :: Int -> a Source #

Produce a variable without name suggestion.

debruijnNamedVar :: String -> Int -> a Source #

Produce a variable with name suggestion.

deBruijnView :: a -> Maybe Int Source #

Are we dealing with a variable? If yes, what is its index?
