            Bug ID: 155807
           Summary: [ES6] Add Proxy based tests for
                    RegExp.prototype[@@match]
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: msaboff at apple.com

In <https://bugs.webkit.org/show_bug.cgi?id=155711> after change set r198554 was landed, it was suggested that we add more Proxy based tests to verify standards conformance.  This would include handling the semantics issue raise in this comment:

> Also, I'm not sure this is correct. You're calling "get" twice here. That is
> an observable
> operation. It looks like RegExpExec only does this get once in the spec.
