            Bug ID: 242631
           Summary: Optimize some array operations by bypassing Identifier
                    creation/destruction
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: darin at apple.com

Some array operations are unnecessarily converting array indices into identifiers. Apparently at some point someone refactored to handle 64-bit integers, and moved the conversion to Identifier too soon.
