Optimal Representations of Polymorphic Types with Subtyping (Extended Abstract)
Optimal Representations Polymorphic Types Subtyping (Extended Abstract)
2016/5/24
Many type inference and program analysis systems include notions of subtyping and parametric polymorphism. When used together, these two features induce equivalences that allow types to be simpli ed b...
