In C, continue does indeed jump to the end of the loop, just before the test.

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 :)
