> Wow, thanks. I'll refactor with this, then.

please test thoroughly, I just hacked the code into my mobile as an example ... be also careful about the numbering of the captures or use an (?:...) for non-capture in the negative list.

I can't follow, since you are using the /g modifier, each iteration will only capture 2 groups and then continue where it left of.

hence my ( $c, $r ) = ( $data =~ /^(\d+) (\d+)/mg ) should nicely do.

(Haven't tested the performance, but every statement normally counts)

> I'll refactor

You initially said that performance wasn't an issue and you were just curious.

I'd rather recommend to go for the clearest code, not for the fastest. Because in the long run maintenance costs you the most.
