I never knew that (I rarely use do/while); I would have assumed it does another iteration of the loop. I agree that this is unintuitive to me, but others seem to think this is the right behavior and C compatibility is important so it should probably be left as-is.

I like the "goto do"/"goto while" option. It's congruent with "goto case"/"goto default".
