In homological algebra, the relationship between currying and uncurrying is known as tensor-hom adjunction. Scala also support multiple parameter lists as currying, e.g. . The latter notation is especially useful in combination with the currying isomorphism. Omitting parentheses is more common, because multiple argument functions can be defined using currying. Currying and partial function application are often conflated. Herzl's currying the Sultan's favor did not go without protest. They only accept one input variable, with currying used to implement functions with several variables. Currying then endows the language with a natural product type. Multi-parameter functions can be represented via the method of currying. Given a function of type formula 144, currying produces formula 145. Historically Azeris of Dagestan were engaged in carpet weaving, currying, jewellery- and copper utensils making. Partial application is sometimes incorrectly called currying, which is a related, but distinct concept. In this Scheme example, the higher-order function codice 6 is used to implement currying. Some notable examples include closures and currying. An interesting operation on functions was "partial application", (sometimes referred to as "currying").
