A hash won't resolve to HASH(0x814dc30) in list context; that's the stringification of a reference to a hash. Hashes flatten and return their keys and values in list context.

    The cute thing here is that the hash is initialized with a list of one item, a reference to an empty hash. So:

    $ perl -e '%foo = {}; print %foo, "\n";' HASH(0x814dc30)

    and (note the trailing comma, indicating an undefined value):

    $ perl -e '%foo = {}; print join(",", %foo), "\n";' HASH(0x814dc30),

    print "Just Another Perl Adept\n";
