As Michael said, this belongs on python-ideas, but it's interesting. I'd
support it, though my input in that regard is worth approximately $0.00. ;)
It's the core devs and especially the eventual BDFL replacement whom you
would have to convince.

Without getting into an extended discussion here on python-dev, I'd like to
offer one brief comment to try to help improve the proposal:

I would argue for non-fallthrough as the default with support for
explicitly requesting fallthrough when desired by using "continue". I don't
know of any prior art for doing it that way, but it makes sense to me. It
eliminates hidden bugs from missing a "break" while still allowing it when

Good luck with the proposal!
