Flycheck-raku module for MELPA

Re: IO ???

Re: need sort help

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,
