Capture group numbering begins at 1, not 0, so the capture group variables corresponding to the capturing groups in the example would be $1 .. $8. In the  @- and  @+ arrays, the offsets of the entire match are held at index 0. Otherwise,  $0 holds the script name. See Variables related to regular expressions and perlvar in general.

Update: The [originally posted] question was for a match in list context ... which returns the matches as a list into an array. Quite right; my mistake.
