Godel’s System T is the simply typed lambda calculus extended with numbers and an iterator. The higher-order nature of the language gives it enormous expressive power. The language can represent all the primitive recursive functions and beyond, for instance the Ackermann function is representable. In this work we use System T as a minimalistic functional language. We give a reversible interpretation using a data-flow model that incorporates ideas from the geometry of interaction and game semantics. The contribution is a reversible model of higher-order computation which can also serve as a novel, although not very practical, compilation technique.
