WebThe recent idea of graded modal types provides a framework for extending type theories with quanti-tative reasoning principles. The Granule language explores this idea in the context of linear types. In this practical setting, when composing programs it is often necessary to distribute algebraic data types over graded modalities, and vice versa. WebGerty.

Webgraded modal types provide an expressive type theory for quantitative program reasoning, advancing the reach of type systems to capture and verify a broader set of program properties. We demonstrate this approach via a type system embodied in a fully-ledged functional language called Granule, exploring various examples. WebGerty has some similarity to Granule [46]: both are functional languages with graded types. However, Granule has a linearly typed core and no dependent types (only indexed types), thus has no need for resource tracking at the type level (type indices are not subject to tracking and their syntax is restricted). 2 GrTT: Graded Modal Dependent ...
