UFCS is particularly useful when function calls are chained (behaving similar to pipes, or the various dedicated operators available in functional languages for passing values through a series of expressions). It allows free-functions to fill a role similar to extension methods in some other languages. Another benefit of the method call syntax is use with "" in IDEs, which use type information to show a list of available functions, depen
