It doesn't seem right to me that until has access to the inner scope of
the loop; isn't that violating the scope or something like that?
Also, is the issue with coninue this?
repeat
code()
if blah then contiue end
local i
more_code()
until i
Or with this?
repeat
local i
code()
if blah then continue end
more_code()
until i
Or both? I'm not sure what the problem is. In C, a continue in a "do ...
while" skips the conditional test. Is the issue the conditional test? Or
the creation of the locally scoped variable?
