===Typed Functional Programming===
Two mechanisms were proposed for adding types to the λ-calculus:
* Church suggested explicit type annotations on all terms
* Curry suggested inferred types
Either way, we lose some properties of the untyped λ-calculus (there's no type for the Y-combinator, for instance!). Nonetheless, the benefits of [[Programming_Language_Theory#Typing typing]] lead to most functional programming languages making use of a strict typing system.
