in thread Determining which pattern matched

I've just wanted to demonstrate the technic without much clutter, but you're absolutely right. I should take care to demonstrate the best practice which is using local our instead of my along with (?{ }).

Here's a great thread explaining the reason behind this for the interested monks (including ikegami's notes): Regexes: finding ALL matches (including overlap).

Replies are listed 'Best First'.

    My comments in that thread were on an entirely different matter (handling backtracking through (?{}), which isn't an issue in the code here), but blokhead mentioned the issue with lexicals in that thread.
