Two agenda were proposed for adding types to the λ-calculus:
* Church suggested explicit type annotations on all terms (simply-typed λ-calculus (λ<sub>→</sub>), "simple" due to single type constructor →)
* Church suggested explicit type annotations on all terms (simply-typed λ-calculus (λ<sub>→</sub>), "simple" due to single type constructor →)
* Curry suggested inferred types (now implemented via techniques such as [http://en.wikipedia.org/wiki/Hindley-Milner_type_inference Hindley-Milner])
