? It is assuming that argv[0] to be an instance of subclass of Module,
this means Foo in

  begin
    ...
  rescue Foo
    ...
  end

to be a module or a class, not that Exception to be a subclass of
Module, but Exception to be an instance of a Class, which is true even
within the sandboxes I guess.  Am I missing something?
