One thing I'd like to add is that returning a hash reference allows for beatiful syntax when you're using a single element from it.
sub hash { qw(foo bar baz xyzzy) } sub hashref { return { qw(foo bar baz xyzzy) } } my %dummy = hash; $dummy = $dummy{foo}; # Afaik, there is no direct syntax to get a single element # but with hash refs, there is: $dummy = hashref->{foo} # equals $dummy = ${ hashref() }{foo}, which is ugly.
