you and marcus are tied for first with the same answer.
is there any guarantee of evaluation order in arg lists? will the
bless/splice always be executed before the pop?
my longer but amusing answer is this:
sub new {
[EMAIL PROTECTED]
}
it is not warning safe and it leaves '' => CLASS in the hash. but it has
no temp vars, calls to splice or shift.
