Functions on abstractions

absApp :: Subst a => Abs a -> SubstArg a -> a Source #

Instantiate an abstraction. Strict in the term.

lazyAbsApp :: Subst a => Abs a -> SubstArg a -> a Source #

Instantiate an abstraction. Lazy in the term, which allow it to be IMPOSSIBLE in the case where the variable shouldn't be used but we cannot use noabsApp. Used in Apply.

noabsApp :: Subst a => Impossible -> Abs a -> a Source #

Instantiate an abstraction that doesn't use its argument.

absBody :: Subst a => Abs a -> a Source #

mkAbs :: (Subst a, Free a) => ArgName -> a -> Abs a Source #

reAbs :: (Subst a, Free a) => Abs a -> Abs a Source #

underAbs :: Subst a => (a -> b -> b) -> a -> Abs b -> Abs b Source #

underAbs k a b applies k to a and the content of abstraction b and puts the abstraction back. a is raised if abstraction was proper such that at point of application of k and the content of b are at the same context. Precondition: a and b are at the same context at call time.

underLambdas :: TermSubst a => Int -> (a -> Term -> Term) -> a -> Term -> Term Source #

underLambdas n k a b drops n initial Lams from b, performs operation k on a and the body of b, and puts the Lams back. a is raised correctly according to the number of abstractions.
