9. Let match be ? RegExpExec(R, S).
Runtime Semantics: RegExpExec ( R, S )
1. Assert: Type(R) is Object.
2. Assert: Type(S) is String.
3. Let exec be ? Get(R, "exec").
4. If IsCallable(exec) is true, then
a. Let result be ? Call(exec, R, « S »).
b. If Type(result) is neither Object or Null, throw a TypeError exception.
c. Return result.
