so you are replacing the question "where does it go to"
that can be answered with a string search wiht "where
does it break to"

This one alone justifies at least labeled breaks as
JAVA has them and that are a kind of restricted GOTO
(as you can also break out of an if)

The JAVA approach is even superior to PHPs "break n;"
where n has to be an integer and you have to be very
carefull to not wrap another loop around the break
but within the loop supposed to be broken
