[Zope] Zope supports Python builin functions?

Hi, Does Zope support Python builtin functions outside External Methods? I made a DTML Methode with juste one line: <dtml-var "4==5"> after clicking on the view tab I got: 0 Perfect. Then I change the line to: <dtml-var "type([])==type({})"> Viewing it displays: ************ Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: type etc....... ************ I know the test is stupid, i just wanted to know if it was possible to use Python builin function inside a simple DTML Method. I understand it's not. Is it right?
