Supports both ``list`` and ``dict`` semantics for ``pop()``. If passed no argument or an integer argument, it will use ``list`` semantics and pop tokens from the list of parsed tokens. If passed a non-integer argument (most likely a string), it will use ``dict`` semantics and pop the corresponding value from any defined results names. A second default return value argument is supported, just as in ``dict.pop()``.
