I still hope that we might be able to convince the Lua authors to add continue one day. It would be very convenient.

I think the real reason why it hasn't been added to the language yet is that it has a weird interaction with the way Lua scopes its repeat-until loops. The justification about having a single control-flow structure is more of an excuse.

As a contrasting opinion, I would like the break keyword to be formally defined as a sugar for a special labeled goto.

Since it's a keyword, you can't create your own ::break:: label, so that would be fine.

I'd be OK with that. But let me type `break` and `continue`, with all the sugar that entails :)
