Maybe you're really after m/\G.../gc ? start the next match on the same string where the last match left off?

see Re^2: Help with regular expression, perlfaq6#What good is \G in a regular expression?

    I try to match only once... but to become faster I try to cut unmatchable stuff at the beginning of my search string so that the next try needn't to start from the beginning again.

    At the moment there are some doubts if cutting really makes things better but that is what I see here.
