and if you do the structure idea you don't need this either

i don't understand 'stop now'. last/next/redo can take a loop label so
you can choose which loop's flow you are controlling. in general with
perl and those flow control ops, you never need to loop over a flag. in
other langs it is about the only way to do it and i feel it is very
clunky style in perl.

there is. see my comments above.
