[New-bugs-announce] [issue25683] __context__ for yields inside except clause

[Yury Selivanov]

New submission from Yury Selivanov:

In the below snippet, SubError will propagate with __context__ set to None, instead of MainError.  Maybe this isn't a bug?

    class MainError(Exception): pass
    class SubError(Exception): pass

    def main():
        try:
            raise MainError()
        except MainError:
            yield

    coro = main()
    coro.send(None)
    coro.throw(SubError())
