[issue46431] Trouble subclassing ExceptionGroup

New submission from Petr Viktorin : I want to test a web application by crawling every reachable page. If an error occurs, I need to keep track of the page the error occured at (and additional info like what links were followed to get to the page, so a `__note__` string isn't enough). This

[issue46399] Addition of `mapping` attribute to dict views classes has inadvertently broken type-checkers

Serhiy Storchaka added the comment: I share concerns of Inada-san. I also think that keeping a status quo (ignoring the mapping attribute in typing) is the lesser evil. I am not sure that exposing this attribute was a good idea. We do not expose attributes list and index for list iterators.

[issue46422] Why do we need `dis.Positions`?

Batuhan Taskaya added the comment: The initial aim of the dis.Positions was to provide an interface like AST nodes. So you could do for instr in dis.Bytecode(source): print("located in: ", instr.positions.lineno) instead of for instr in dis.Bytecode(source): if instr.positions:
