there i was copying the "accept()" method from here:
https://sbcode.net/python/visitor/#visitorvisitor_conceptpy

i don't actually like the name of the function, but the *separation*
of the actual-walking, that's the important bit.

i really like the contextmanager and __call__() here, much better than
"accept()".

it's very subtle, it's part of the "Model View Controller" paradigm.

what you have done is {ModelViewController-all-in-one}
