[Proto-Scripty] nested "each" loops and "throw $break" statement

[Vasily Ivanov]

Hi,

I have two nested "each" loops (possibly more in the future) and I need to
exit multiple levels at once on some condition. I do it like this:

$R(minX, maxX).each(function(x) {
  $R(minY, maxY).each(function(y) {
   ...
   if (someCondition)
    throw $break;
  });
  if (someCondition)
   throw $break;
});

Is it possible to use something like this instead to avoid code duplication?

loopStart:
$R(minX, maxX).each(function(x) {
  $R(minY, maxY).each(function(y) {
   ...
   if (someCondition)
    throw $break(loopStart);
  });
});

I'm using prototype 1.6.0.3.

Thank you,
  Vasily
