 Well, this is not a super interesting interpreter, as it interprets any program to ``0``. To make it more interesting, we could have examined what the structure of ``node`` is, and take different actions according to whether it's a parameter, an enum, or a function application (in which case you may need to recurse down and interpret its arguments).
