Type Inference: Hindley-Milner Overview

This lecture covers type inference in statically typed languages, focusing on algorithms like bottom-up propagation and Hindley-Milner constraint-based inference. It explains how to assign types to program expressions and introduces type rules for variables, constants, pairs, and functions. The lecture also delves into Hindley-Milner type inference, supporting generic structured types and showcasing examples of type inference in programs without annotations.
