Not a very big problem in an External Method:

  You create a Zope Page Template object, wrap it into a context
  (using its "__of__" method) and then call it.

Few chances in an (internal) Python Script, as you will not be allowed
to call "__of__".
Without this "__of__", the template has no way to know its
context (e.g. "here", "container", ...).
