    ... and you don't even need the '+' on the  += operator:

    >perl -wMstrict -lE "my $s = 'abababa'; my $t = 'aba'; ;; my $c = map /(?=$t)/g, qw(abababa ababa); say $c; " 5
      and you don't even need the '+' on the += operator:

      Of course I don't. Much nicer!

[stevieb]: man, I absolutely LOVE driving in the worst winter conditions. In the mountainous roads, there are extremely few (if any) other drivers. I love the challenge. I've been doing extreme off-road my whole life, and as I said, I'm always well...
[stevieb]: ...prepared for even the very worst
Discipulus seems a part of the globe very unfrindly with Kawasaki riders..
[thezip]: My doggies love it when it snows
[perldigious]: As long as you are a good "boy scout" stevieb, more power to you... but I like my Jeep, and don't like the idea of rolling it or crashing it in to anything. :-)
[thezip]: Me, not as much.
[perldigious]: Mine too thezip, especially my German Shepherd. He looks like he is about to die of heat exhaustion all summer, so he goes nuts when winter comes and he can play in the snow.
[stevieb]: my main off-road vehicle nowadays is a strengthened mercedes ML320. I'm very hard on it, but I've never had any real issues at all (I love how small and light it is, and it has a very, very good centre of gravity for how I roll)
