| /** |
| * @assertion Evaluation of an ordinary method invocation i of the form |
| * o.m(a1 , . . . , an , xn+1 : an+1 , . . . , xn+k : an+k) |
| * proceeds as follows: |
| * First, the expression o is evaluated to a value vo. Next, the argument list |
| * (a1 , . . . , an , xn+1 : an+1 , . . . , xn+k : an+k) is evaluated |
| * yielding actual argument objects o1 , . . . , on+k . Let f be the result of |
| * looking up method m in vo with respect to the current library L. |
| * Let p1 . . . ph be the required parameters of f, let p1 . . . pm be the |
| * positional parameters of f and let ph+1 , . . . , ph+l be the named |
| * parameters declared by f. |
| * If n < h, or n > m, the method lookup has failed. Furthermore, each |
| * xi , n + 1 <= i <= n + k, must have a corresponding named parameter in the |
| * set {ph+1 , . . . , ph+l} or the method lookup also fails. Otherwise |
| * method lookup has succeeded. |
| * If the method lookup succeeded, the body of f is executed with respect to |
| * the bindings that resulted from the evaluation of the argument list, and |
| * with this bound to vo. The value of i is the value returned after f is |
| * executed. |
| * @description Checks that the method lookup fails if a form o.m() has a |
| * parameters mismatch listed above with the vo class's instance method. |
