again, i haven't implemented this, but break would be supported by
having watch() return a custom Iterator that can be prematurely
finished. i can't see anyway to implement "continue" without
modifying the core engine or a custom directive.

i'm planning to keep references to the watched iterators in the tool
within a stack. should make it easy to support nested loops, as
break() would just stop the iterator on top of the stack. this might
also support a breakAll() or even allow watch($list, 'label') ->
break('label') without much effort.
