Re: Re: Hash references moving between modules

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,
I noticed that a while after I wrote it. I guess I'm too used to using ->.. I think thats more readable than $$ ..
