Isn't it awkward that one needs to invent workarounds such
as tail calls or coroutines or artificial extra loops just
to not use such a basic thing as the "continue" statement?

IIRC, the "continue" patch adds only 3 or so lines to the lua sources.
No, I don't consider "continue" as contamination of lua.
I very much hope to see "continue" as part of lua some time.
