**ML**is a general-purpose functional programming language developed by Robin Milner and others in the early 1970s at the University of Edinburgh, whose syntax is inspired by ISWIM. Historically, ML stands for*metalanguage*: it was conceived to develop proof tactics in the LCF theorem prover (whose language,*pplambda*, a combination of the first-order predicate calculus and the simply typed polymorphic lambda calculus, had ML as its metalanguage). It is known for its use of the Hindley–Milner type inference algorithm, which can automatically infer the types of most expressions without requiring explicit type annotations. Additionally, the use of this algorithm ensures type safety — there is a formal proof that a well-typed ML program does not cause runtime type errors.^{[1]}
