            Bug ID: 155590
           Summary: The concat fast path should use "in" instead of a
                    getbyid === undefined
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: keith_miller at apple.com

We use getbyid === undefined because switch to in is a 10% regression on the stanford-crypto tests. We should notice in the DFG that an in on an id is a constant and fold it.
