Excuse my ignorance wrt. to Python, but to me this seems to imply that
one of these statements about functions in Python are true:

  1. Function names (strings) are resolved (looked up in the
     namespace) each time a function is called.

  2. You can't really undefine a function such that existing calls to
     the function will be affected.

Is this (i.e. one of these) correct?
