           Summary: Strict functions claim to have 'callee' which they
                    actually don't (and shouldn't)
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: erights at gmail.com


> function foo(){"use strict"}

> Object.getOwnPropertyNames(foo)
["arguments", "callee", "caller", "length", "name", "prototype"]

> Object.getOwnPropertyDescriptor(foo, 'callee')
undefined

> 'callee' in foo
false

> foo.hasOwnProperty('callee')
false

I suspect this may be due to a partial misreading of the ES5/strict poisoning rules, where we poison "callee" and "caller" on arguments, but poison "arguments" and "caller" on strict functions.
