Lecture 19: Subtyping
We introduce subtyping as another extension to the Mini-ML type system.
Subtyping allows us to capture more information about the program, but leads
to a more complex type inference problem. In this lecture we limit ourselves
to so-called atomic subtyping. We show how to extend the proof of
type preservation and the language of constraints required to express
type inference.
