my ($class,$d) = shift;

in my understanding, this "initializes" $d with undef. Why don't you 
      my ($class,$d) = @_;

Personally, I'd do it this ("mixed") way:
      my $class = shift;
      my ($args, $as, $needed) = @_;

to have the argument list in the same manner as in the corresponding method call.

Update: see also this discussion from several years ago

Update: typo corrected. Thanks AnomalousMonk!
