           Summary: reduce and reduceRight bind callback's this to null
                    rather than undefined
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Trivial
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: erights at gmail.com


Both
    [2,3].reduce(function(){'use strict';return this;})
and
    [2,3].reduceRight(function(){'use strict';return this;})
return null rather than undefined. This violates step 9.c.ii of sections 15.4.4.21 and 15.4.4.22 of ES5.1.
