You need to soften your rocks of certitudes, Bearophile.
cycle
(action0)
if condition continue/break
action
is a common scheme. Existence of continue/break allows simple, clear, correct
expression of this scheme. By "correct", I mean they mirror what they mean.
Without them, we are left to _wrong_, or even more wrong, convolutions that do
not easily show the sense of the code.
Either there is no structured programming structure to idiom for that, or it is
precisely using those magic keywords. Lua has no continue: it is a pain and a
constant request (even if far less often needed than break).
Byt I agree the originally posted code did not require it.
