This notation: @hash{ }
is a hash slice. See `perldoc perldata` and search for "Slices".
it will return the values of a hash that correspond to the keys inside
the curly brackets.
Example:
#!/usr/bin/perl
use strict;
use warnings;
my %hash = (
a => 1,
b => 2,
c => 3,
);
my @values = @hash{ 'a', 'c' };
print "values for 'a' and 'c': @values\n";
@values = @hash{ 'a' .. 'c' };
print "values for 'a' to 'c': @values\n";
