Description:
 def unoptimize_scope(self, frame):
 """Disable Python optimizations for the frame."""

        # XXX: this is not that nice but it has no real overhead.  It
        # mainly works because python finds the locals before dead code
        # is removed.  If that breaks we have to add a dummy function
        # that just accepts the arguments and does nothing.
