def __init__(self, inner):
        """ Takes a reference to a Yay AST node """
        self.inner = PythonicWrapper(inner)
        self.inner.parent = inner.parent
        self.observers = collections.defaultdict(list)

        for k in dir(self):
            prop = getattr(self, k)
            if isinstance(prop, Property):
                i = getattr(self.inner, k)
                i.inner.parent = inner.parent
                i.parent = inner.parent
                p = prop.klass(self, i, **prop.kwargs)
                setattr(self, k, p)
