'''Uniform Function Call Syntax''' (UFCS) or sometimes '''Universal Function Call Syntax''' is a [[programming language]] feature in [[D (programming language)|D]], [[Rust (programming language)|Rust]]<ref>https://doc.rust-lang.org/book/first-edition/ufcs.html</ref> and [[Nim (programming language)|Nim]] that allows any [[function (computer programming)|function]] to be called

using the syntax for method calls (as in [[object-oriented programming]]), by using the [[receiver (object oriented programming)|receiver]] as the first parameter, and the given arguments as the remaining parameters.<ref>http://dlang.org/function.html#pseudo-member</ref> UFCS is particularly useful when function calls are chained,<ref>http://ddili.org/ders/d.en/ufcs.html</ref> (behaving similar to [[Pipe (computer science)|pipe]]s, or the various dedicated [[Operator (computer programming)|operator]]s available in [[functional language]]s for passing values through a series of [[Expression (computer science)|expression]]s). It allows free-functions to fill a role similar to [[extension method]]s in some other languages. Another benefit of the method call syntax is use with "[[dot-autocomplete]]" in [[IDE (computing)|IDE]]s, which use type information to show a list of available functions, dependent on the context. When the programmer starts with an argument, the set of potentially applicable functions is greatly narrowed down<ref>{{cite web|title="Unified Call Syntax"|url=https://isocpp.org/files/papers/N4165.pdf}}</ref>, aiding discoverability.
