Hi all,
I apologize in advance for the "foggy"
question, but I've myself unclear ideas.
Anyway...
Python has "context manager".
For example, the "open()" class can be
simply used as follow:
with open(...) as fp:
fp.do_something()
On the other hand, it is also possible to do:
fp = open()

You can use `with` in classes -- with any context manager.
However, you would usually not use `with` with a file you have opened
in `__ini

Dave,
Back on a hopefully more serious note, I want to make a bit of an analogy
with what happens when you save data in a format like a .CSV file.
Often you have a choice of including a header line giving names to the
resulting columns, or not.
If you read in the data to some structure, often to

He knows that. The OP wrote that he wants to use that can
_only_ be used by a context manager, but he wants that us

Yes, "been" is the past participle of 'to be", so "I've been" is
fine.

It should be possible to run the context protocol yourself.
Something like (warning, untested):
