fun <A1, A2, R> f2(f: KFunction2<A1, A2, R>, a1: A1, a2: A2): MetaFeature<R> (source)

Creates a MetaFeature for the given function f which expects 2 arguments.

Notice for expectation function writers: you should use feature and pass a class reference instead of using this convenience function (e.g. feature(MyClass::fun, ...)). This way we are always able to report the function name, even if the subject is not defined which occurs if a previous transformation of the subject could not be carried out.
