Hmm... Well, derefrencing a hashref can be done in the way you showed up there, but it is perfectly valid to get a scalar back from a hashref this way as well:
$scalar = $$hashref{key};
and assigning into a hashref can be done in the same way:
my $hashref = {}; $$hashref{key} = $scalar;
Perhaps taking a look at References quick reference will sum it up nicely.

Thanks,
