- Is it cool to populate a hash of arrays with qq or qw? 
e.g.

my %animals = (
  pets => [ qw(cat dog) ],
  non  => [ qq(rhino giraffe) ],
);

- If one of those is correct what goes in the blank if I want to iterate through one of the arrays? 
    foreach $i (???) {
        push ( @some_animals, $animals{pets}[$i] );
    }
