Okay, but surely the reference to restricted execution objects is now
wrong? Can you give me corrected text for the para in question?

Each function gets its own restricted execution object in the
Python interpreter, so that global data and function arguments from
<function>myfunc</function> are not available to
<function>myfunc2</function>. The exception is the data in the
<varname>GD</varname> dictionary, as mentioned above.
