This is very interesting. But I wonder how it works. I can understand the first
line
my ($month, $day, $year, $hour, $minute, $second) = .comb(/\d+/);
Which extract the variables from $_. What is the second line doing, it is very
concise.
($year // 0, $month // 0, $day // 0, $hour // 0, $minute // 0,
$second // 0, $_);
Could somebody explain in some more words.? What does // do? Why it sorts the
array?
Regards
