in reply to Perl Bug in Regex Code Block?

I may be confussed, but i think the problem is with the :
my @counts = (0);

... specifically, the my. When you use my, you are creating a variable which will disappear when it goes out of scope. since the for (0..2) {} loop is the current scope, when it completes, @counts is destroyed. This is fixed by not using a my inside of the for loop (as you have seen), and is a very perlish thing.

    I'm well aware of that ... but the regex is taking place inside this scope and so the lexical variables should be accessible inside the regex. This works the first time as expected but it doesn't work on the second and third iteration of the loop.

    Maybe you have misunderstood my question, I'm not confused that the last line of my code doesn't print anything. It was only included for the (working) run with our instead of my. I want to know, why it's changing its behaviour inside the loop.

    I hope this clarifies my problem ...
