Having said that,

$a = []; print scalar (@$a), "\n";
$a = undef; print scalar (@$a), "\n";

results in: "0" and "" being printed with no warnings.

$a = []; print int(@$a), "\n";
$a = undef; print int(@$a), "\n";

results in "0" and "0" being printed, again with no warnings.

In general, I'd like things to behave in a Perl like fashion, including
"auto-vivification" of CORBA data structures as necessary.
