A question of idle (and perhaps rather trivial) curiosity: In the quoted code, you use $-[0] "offset of the start of the last successful match" (see @- in perlvar). My reflexive choice would have been $-[1] since capture group 1 is being matched. There's no difference in the behavior of the code since capture group 1 is all that's matched, but was there a particular reason you chose as you did?
