Seems that the semantics of globalEval are also a bit confusing. The  
code passed to it is evaluated but the value of the last expression  
isn't returned.

#asJavascript returns the method/function as a String but I forgot  
that self is bound to this which will be window in the function.

The code below works for me in Safari, but yes it's really creepy :-)

- perform: selector with: anObject

	| method evalString |
	@class withAncestors do: [:ea |
		(ea methodAt: selector) ifNotNilDo: [:m | method := m]].
	method ifNil: [self error: 'Method ' , selector , ' not found!'].
	performSelf := self.
	evalString := 'performResult = (' , method asJavascript ,  
').call(performSelf,' , anObject , ')'.
	evalString globalEval.
	performResult.
