            Bug ID: 187758
           Summary: Inconsistent output compared with other JS engines
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org

Hello,
The following code behaves strangely (inconsistent with other engines).

class c {                                                                                                                                        
    [d = function () {
        return c;
    }]() {
    }   
}

print("BT_FLAG");
In JavaScriptCore, the output is
BT_FLAG
However, in V8 and SpiderMonkey, output is
ReferenceError: d is not defined
