I'm not sure what you mean by limited goto, but your example works since
ES3 in JS. Underused part of the design: break from labeled block or if,
no need for do-while(0) nonsense.

Dijkstra has written his essay on unlimited goto, that could jump from
any point in code to any other point in code.
I don't see reason why limited "goto" that is semantically equivalent
(or little more powerful) to
x: do {
continue x;
} while(false);
should be considered harmful (anyway - it's useful almost only for
implementing state machines).
