# Maps over Core expressions

data CoreMap a Source #

`CoreMap a` is a map from `CoreExpr` to `a`. If you are a client, this is the type you want.

# Maps over `Expr`s

data TypeMap a Source #

`TypeMap a` is a map from `Expr` to `a`. If you are a client, this is the type you want. The keys in this map may have different kinds.

lookupTypeMap :: TypeMap a -> Type -> Maybe a Source #

foldTypeMap :: (a -> b -> b) -> b -> TypeMap a -> b Source #

data LooseTypeMap a Source #

A `LooseTypeMap` doesn't do a kind-check. Thus, when lookup up (t |> g), you'll find entries inserted under (t), even if (g) is non-reflexive.

## With explicit scoping

data CmEnv Source #

lookupCME :: CmEnv -> Var -> Maybe BoundVar Source #

extendTypeMapWithScope :: TypeMap a -> CmEnv -> Type -> a -> TypeMap a Source #

Extend a `TypeMap` with a type in the given context. `extendTypeMapWithScope m (mkDeBruijnContext [a,b,c]) t v` is equivalent to `extendTypeMap m (forall a b c. t) v`, but allows reuse of the context over multiple insertions.

lookupTypeMapWithScope :: TypeMap a -> CmEnv -> Type -> Maybe a Source #

mkDeBruijnContext :: [Var] -> CmEnv Source #

Construct a deBruijn environment with the given variables in scope. e.g. `mkDeBruijnEnv [a,b,c]` constructs a context `forall a b c.`
