           Summary: window.self is set to window
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: spamfaenger at gmx.de


Strangely enough window.self is existing and points back to window - this has
the unfortunate side effect that the very common pattern of doing 

var self = this;
function callback(someValue) {
    self.value = someValue;
}

fails in often very subtle ways if one mistypes or forgets self in the initial
assignment.

This error would be much easier to spot, if window.self would return
'undefined'.

(Also I think that the dom spec doesn't entail window.self to be set - Firefox
for example doesn't have it.

Please also be aware that this variable actually also exists already in Safari
4.0.3
