Why not a combination of the two solutions, something like:

sub yoink {
  my ($array_ref, @kill_patterns) = @_;
  foreach my $kp (@kill_patterns) {
    @{$array_ref} = grep $_ ne $kp, @{$array_ref};
  }
}
[download]

That way, you could call it with one or more kill patterns, such as &yoink(\@arr, $kp), or &yoink(\@arr, $kp1, $kp2, $kp3), or so forth... (At least, I think it would work....)
