Arguments
| :: (Typeable ra, Typeable a, Typeable rb, Typeable b) | |

Let binding
shallowApply :: Lam expr (ra -> rb) (a -> b) -> Lam expr ra a -> Lam expr rb bSource
Shallow application. Function argument must be a Lambda.
Arguments
| :: ExprShow expr | |
| => [String] | Missing arguments |
| -> Lam expr role a | Partially applied expression |
| -> State Integer String |
Shows a partially applied expression
Arguments
| :: ExprShow expr | |
| => Forest String | Missing arguments |
| -> Lam expr role a | Partially applied expression |
| -> State Integer (Tree String) |
Converts a partially applied expression to a tree
lamToTree :: ExprShow expr => Lam expr role a -> State Integer (Tree String)Source
Converts a lambda expression to a tree
showLamTree :: ExprShow expr => Lam expr role a -> StringSource
Show a lambda expression as a tree
