why's a "help us fix bugs related to exception handling" proposal
getting so much pushback? I don't understand.

this is a bigger problem in the context of massive frameworks, where you
can have layers upon layers of exception handling for all sorts of
different stuff. everything from catching KeyError to skip missing
entries in a dictionary, in template engines, to... honestly idk what
else those massive frameworks like to skip, but I regularly see ppl
complaining that their framework's exception handling makes their code
undebuggable. and I've been paying attention to python's IRC for years.
it's a real problem. I can't be the only person who has noticed this.

sure, these language changes wouldn't magically solve that problem. but
currently you can't solve the problem *at all* because there's no way to
tell anything apart. the language changes would just be a step in the
right direction.

opinions? bikesheds? bring it forward. don't just keep it to yourself.
