Please reconsider your attitude to this issue; there is no acceptable
defense to your response-- it is flagrantly rude and disrespectful to
someone trying to help you. Perhaps you don't appreciate their perceived
tone when you repeatedly don't listen to people telling you that this just
isn't a place to go, but even if that tone was there, its not even kind of
OK to respond the way you did. You don't really get points for not being an
ass sooner: that's not tolerance.

To your issue, while I don't believe traceback.extract_stack will be going
away anytime soon, the use of it for your purpose is something you can't
rely on. It works, kind of, because exceptions keep a stack of frames which
are examinable -- for the purpose of printing tracebacks.

It might work, kind of. In a strictly controlled set of circumstances (which
Gabriel articulated) that 'kind of' might be good enough for you. If you're
a closed-source or purely internal application in which you have complete
control of the scenarios of use, that might be fine. If you intend for
anyone else to ever use it or to let this code out of strict control though,
then it's an unmitigated mistake to take this approach.

You're working directly *against* the language, its entire design and
function. You can kind of achieve your result: but its a hack. Some hacks
are necessarily evils sometimes, certainly. But they are always fragile.

Instead of insulting Steven D'Aprano, perhaps it would be better to answer
his question. What are you REALLY trying to solve? What are you REALLY
needing to do? Why do you so need to do this?
