Webbtype substitution f 7!Zgand inserting coercions, but the naive algorithm can only infer the type of the rst term. Since the term is an application, the algorithm would rst infer (using standard Hindley-Milner type inference) that the function denoted by the subterm leq [ 7! ] ihas type Z !B with the type substitution f 7!Zg. Similarly, WebbHindley-Milner constraint solving algorithm like union-find. We are leaning towards the first idea but may revert to the latter depending on time/difficulty.

Hindley milner algorithm

WebbTo be precise, Hindley-Milner is a unidirectional algorithm because it only infers types; it doesn't check against type annotations. Hindley-Milner is actually a delicate balance between simple and advanced type systems. Once you add fancier features, type inference without type annotations becomes undecidable.

The origin of this algorithm is the type inference algorithm for the simply typed lambda calculus that was devised by Haskell Curry and Robert Feys in 1958. In 1969 J.
