In Python2.1/Zope 2.4, it will work.

In older Python versions, you have only 2 scopes:
  function local and module global.

The body of a Python script is a Python function body.
You are in the function local scope.
Inside a local function definition, you see only it own
local definitions and the global module ones but not
the local definitions in the enclosing scope.

This will change with Python 2.1 nested scope support.
