The DeepArrow package

[Tags:bsd3, library]

This library provides a framework for type-directed composition of value editors (non-syntactic transformations). The tools enable "deep function application" in two senses: deep application of functions and application of deep functions. These tools generalize beyond values and functions, via the DeepArrow subclass of the Arrow type class.

For more information see:

The primary module is Control.Arrow.DeepArrow. Examples in Control.Arrow.DeepArrow.Examples.

Note: Many of the type signatures use infix type operators (as in a~>b). In reading the documentation and code, be aware that infix operators bind more tightly than ->.
