Well, as this is exactly what I proposed just yesterday, I'm + several thousand for it (modulo my fairly nonexistent karma!).  I'd love to see this implemented regardless of what happens to goto, as I completely don't care whether PHP has goto or not.

I'm fairly agnostic on which syntax to use, although I see some benefit in distinguishing break labels from goto labels.  I do quite like the "as" suggestion -- it seems really clear and readable.

Mmmm -- not too sure about this.  As you say, it possibly has slightly too much WTF potential.
