This is precisely the problem. You are emulating 'continue' at the
cost of loosing 'break' operation. The goal is to have them both doing
their respective things within the same loop.

Regarding 'repeat...until'. I am not using it at all. Mentally, I am
always tempted to write 'repeat...until false' where I am supposed to
write 'repeat...until true'. Having been bitten by this issue several
times I ceased to use 'repeat...until' altogether replacing it with
'while true do ... if something then break'.
