Will python never intend to support private, protected and public?

This notion isn't so bad, if there's way for modules to notice when
they're spied on, like an import hook, e.g.:

  def __spy__(othermodule, symbol_list):
     # this gets called when another module spies on symbols

It's like a runtime version of C++'s "friend" declaration.  Well, not
quite as good, it's like having some stranger slide over to you in a
bar and say "I wanna be your friend".  But at least it's better than
not finding out at all where the external references are.
