Right. I mean, consider your simple python:

    with some_resource() as resource:
        some_function_on(resource)

Is that broken? If some_function_on saves the resource, yes. If it just temporarily uses it, no.

I don't think the claim that it's syntactically obvious in Python is correct. In both cases the typical syntax helps a little but it's easy to get wrong.

It is the case that "the typical syntax" is a little more enforced by Python-the-language.
