            Bug ID: 192830
           Summary: Annex B.3.5: Var-redeclaration of a catch parameter in
                    a for-of initializer is a syntax error
           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: ross.kirsling at sony.com

Annex B.3.5 exempts `try {} catch (e) { var e; }` from being a syntax error, but this exemption should not apply if the var declaration is a for-of initializer.
