Textbook: ... What happens when HM type inference is over? Either a "principal type" is found, or a type error has been detected. Textbook: ... Achieving polymorphism for `let` expressions in HM type inference leads to "type schemes", which universally quantify over type ...

A comparison of big-step vs. small-step semantics, and substitution model vs. environment model Textbook: ... Small- and big-step evaluation relations are themselves related: the big-step is an abstraction of the small-step Textbook: ... The `function` keyword provides helpful syntactic sugar for pattern matching. Textbook:
