           Summary: ES6 Set constructor does not follow the spec
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

According to the latest draft of the specification and other implementations of ES6's Set, "new Set" should optionally take an iterable instead of variable arguments. In trunk (and Safari 8 and iOS 8), SetConstructor::constructSet processes variable arguments.

Additionally, calling "Set(...)" should always throw a TypeError regardless of its arguments. Currently SetConstructor::callSet does not raise an exception when invoked as "Set()" without arguments.
