I'm quite getting into the practical uses of the '..' operator, which seemed quite arcane and obscure to me in the past. However, if you want bracketed text, for example when trawling a log file, the flipflop does the business. 
while (<>) {
    if (/BEGIN/ .. /END/) {
        do some stuff
    }
}

But I am wondering if I can use this inside an iterator. I want it to retain its state information between successive calls to the iterator, as to which regexp it is looking for.

But, what's to stop someone from calling my code multiple times: multiple concurrent iterators. Will each flipflop keep track of its own state? What about if the multiple iterators are closures made from the same subroutine (hence same optree) - will this work?

Also, can I save and restore a given flipflop's state?

All help on this is most welcome.
