How does that work?

  It's glob and/or bsd_glob from the underlying C stdlib. Another interesting example of things the stdlib glob can do: #!/usr/bin/perl # perl since it's an easy way to use an arbitrary function from stdlib use File::Glob "bsd_glob"; for (bsd_glob("{Hello,Hi} {world,everyone}...a {demo,example}")) { print($_."\n"); }
