 * @assertion  A function expression invocation i has the form
 * ef(a1, ..., an, xn+1: an+1, ..., xn+k: an+k), where ef is an expression.
 * . . .
 * If ef is a property extraction expression, then i is is not a function
 * expression invocation and is instead recognized as an ordinary method
 * invocation.
 * @description Checks that a.b(x) is parsed as a method invocation of method
 * b() on object a, not as an invocation of getter b on a followed by a
 * function call.
