In list context, //g returns all the matches. This new modifier will only match once, but the next time, it'll start attempting to match where the last one stopped. It's like doing:

while (/pattern/g) {
  my ($x, $y, $z) = ($1, $2, $3);
  # ...
}

except that you can combine the regex and the assignment.
