Strachey's skepticism, however, understates the phenomenon. Ad-hoc polymorphism is not merely syntactic sugar; it is the primary mechanism by which programming languages accommodate domain-specific semantics without surrendering to untyped chaos. In type theory, ad-hoc polymorphism corresponds to the introduction of type-indexed families of functions, and it...)

Ad-hoc polymorphism is the capacity of a single function name or operator to denote different implementations depending on the types of its arguments. Unlike parametric polymorphism, where a single generic implementation operates uniformly over all types, ad-hoc polymorphism selects among multiple concrete implementations at the point of application. The term was coined by Christopher Strachey in 1967, who distinguished it from parametric polymorphism by noting that ad-hoc polymorphism is not
