TILC: The Interactive Lambda-Calculus Tracer1
... TILC is a graphical application that mainly consists of an area where lambda-terms are textually introduced, and a panel where the parse-tree of the term is represented and can be manipulated. The effects of these manipulations are graphically and textually reproduced: sub-term identification, bound ...
