Practical programming with substructural types
Jesse A. Tov · 2012
Substructural logics remove from classical logic rules for reordering, duplication, or dropping of assumptions. Because propositions in such a logic may no longer be freely copied or ignored, this suggests understanding propositions in substructural logics as representing resources rather than truth. For the programming language designer, substructural logics thus provide a framework for considering type systems that can track the changing states of logical and physical resources.
