We have two options: either the continue jumps into the scope of 'x'
bypassing its declaration/initialization (very bad), or the continue
skips the test altogether (very bad too).
So, it seems that continue is incompatible with this scope rule...
What would happen if someone wrote:
repeat
...
if not something then
local x = ...
end
...
until something-with-x
Existing code would not break until someone adds a 'continue', then its
not existing code ...
