context manager's :meth:`__exit__` bound method. Below that are 1--3 values
indicating how/why the finally clause was entered:
- * SECOND = None
- * (SECOND, THIRD) = (WHY_{RETURN,CONTINUE}), retval
- * SECOND = WHY_\*; no retval below it
+ * SECOND = ``None``
+ * (SECOND, THIRD) = (``WHY_{RETURN,CONTINUE}``), retval
+ * SECOND = ``WHY_*``; no retval below it
* (SECOND, THIRD, FOURTH) = exc_info()
In the last case, ``TOS(SECOND, THIRD, FOURTH)`` is called, otherwise
returns a 'true' value, this information is "zapped", to prevent ``END_FINALLY``
from re-raising the exception. (But non-local gotos should still be resumed.)
+ .. XXX explain the WHY stuff!

All of the following opcodes expect arguments. An argument is two bytes, with
the more significant byte last.
