           Summary: Aguments constructor should put 'callee' and 'length'
                    properties in a more efficient way
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cwzwarich at uwaterloo.ca

             nThis:


Currently the Arguments constructor uses putDirect() to put both of these
properties. A Shark profile on my system says that this is 5.6% of total time
in the V8 Raytrace benchmark, which suggests that we should find a better way
to add these properties.
