Which I understand why, but which I think is _the_ stumbling block with the
current threads implementation. And which is something _everybody_ will
bang their head against when they start programming threads... ;-(
Ray, for what it's worth: I get around that by serializing any values with
Storable::freeze and then retrieving the value later again with
Storable::thaw. Maybe a future version of Perl might make this process
automatic, or maybe we could create a tie-able class for hashes, arrays and
scalars. Would that work, Arthur?
