           Summary: Error properties of the Global Object are missing the
                    DontEnum attribute
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: khansen at trolltech.com


The properties "EvalError", "RangeError", "ReferenceError", "SyntaxError",
"TypeError", "URIError" don't have the DontEnum attribute, and consequently
they show up in a for..in statement. According to ECMA-262, chapter 15, these
properties should not be enumerable ("Every other property described in this
section has the attribute { DontEnum } (and no others) unless otherwise
specified").

Curiously, the "Error" property does have the attribute, but the more specific
errors do not.
