Hi Sara,
I made another patch that is based on your ideas.
1) It uses "right" syntax:
LABEL: while(1) {
break LABEL;
}
2) It doesn't allow usage of same label for different loops
L1: while(1) {...}
L1: while(1) {...}
3) It doesn't use executor data structures
4) It allows reuse of sa
thanks for the explanation Sara, :-), as always your manner and ideas
are an example to the 'php core', 'we' (they) are lucky to have you :-)

It occured to me on the way onto the train that this construct doesn't
need pass_two(). When I get home to more bandwidth I'll cook up a
simplified version that resolves break distance in zend_do_brk_cont() and
frees the labels in do_end_loop().
