Types and Expressions,lism used in this chapter is a simply typed λ-calculus , akin to a purely functional programming language without polymorphism. This simple formalism is introduced in a way that makes forthcoming extensions natural. With these extensions we can not only reason logically, but also build complex pcaldron 发表于 2025-3-24 00:39:12
,Dependent Products , Pandora’s Box,tions. This limitation disappears with the introduction of a new type construct, called the .. This construct generalizes the arrow . → . which represents functional types or implications depending on the sort of . and .. With dependent products we can build functions where the result type depends o打击 发表于 2025-3-24 02:40:37

Inductive Data Types,cursive type definitions found in most functional programming languages. However, the possibility of mixing recursive types and dependent products makes the inductive types of . much more precise and expressive, up to the point where they can also be used to describe pure logic programming, in other窒息 发表于 2025-3-24 10:51:13

It is better to rely on the usual programming tools (compilers, abstract machines, and so on) to provide this environment.
