/// @assertion A function expression invocation
/// ef(a1, ..., an, xn+1: an+1, ..., xn+k: an+k) is equivalent to
/// ef.call(a1, ..., an, xn+1: an+1, ..., xn+k: an+k).
/// @description Checks that a function expression invocation ef(...) is indeed
/// equivalent to the ordinary method invocation ef.call(...) and that the result
/// in either case is the same as expected whether ef is a function literal
/// expression or some other kind of expression.
