[Zope] How do I call DTML Method which name is stored in a variable

Hi, Thanks to Evan Simpson, I learned a method can be called in the following way: <dtml-var expr="_.render(FetchObj(_.None, _,fetchStr='hie/dee/hoe').id)"> Suppose the name of the method is stored in a variable. How do I invoke the method? -- Carlos Henrique Bauer
