Parametric Polymorphism and Abstract Models of Storage
... By generalising Plotkin’s logical relations theorem, we can argue that anything definable in a good typed language is parametric. All constructive mathematics is parametric. For example, natural deduction rules are parametric. So are all category-theoretic adjunctions. The rule of excluded middle an ...
