It's impossible to answer you without seeing the source of the whole
interpreter. You have to know precisely which of the four variables
turned into a constant; then it should be easy to follow back why.
Constantness can only follow from translation-time constants, but
sometimes a bit indirectly (e.g. maybe self._arg_stack is a list in
which you only ever put one translation-time constant).
