Indeed it does. But in C, the following is illegal:

do {
  int i = 1;
  // ...
} while(i);

(Or, at least, it refers to a different 'i' than was declared inside 
the loop.) So any 'continue' is in fact jumping to the end of the 
scope, and then executing the test in the surrounding scope.

I'm not suggesting that it was a bad thing to change the scope of 
'until': Diego has a good point about its utility. And Lua does not 
have a 'continue' statement, so the discussion about what its semantics 
might be is completely hypothetical, which doesn't make it less 
interesting :)
