Snippet Pi=3: RFC 2: New port semantics

# an example of the max node's op

def changed(self, inputs):

    # note how this function does not use stateaccess, as it doesn't use state

    return max(inputs.values())

# so, how the heck does this work?

# we check the function to get the names of kw args in the function.

# we always pass self, but everything else is optional

# the node asked for inputs, which looks like this:

# inputs = {'portname' : PortObj, 'portname2', PortObj}

# somehow, the PortObjs are max'ible.
