matcher :: [Match] -> Exp Source #

Simulates lambda-case without the need for extension.

productGetter :: Name -> Int -> Int -> Exp Source #

Lambda expression, which extracts a product member by index.

productSetter :: Name -> Int -> Int -> Exp Source #

Lambda expression, which sets a product member by index.

adtConstructorNarrower :: Name -> Int -> Exp Source #

enumConstructorToBool :: Name -> Exp Source #

singleConstructorAdtToTuple :: Name -> Int -> Exp Source #

tupleToProduct :: Name -> Int -> Exp Source #
