is it possible you can remove the invalid names before going through the list? for example create a new array with the valid names.. find the number of them and then test the id against the array element in your subroutine:

my @raw_names = ...; my @valid_names = (); my $total_valid_names = -1; foreach my $raw_name(@raw_names){ next unless $raw_name; push(@valid_names,$raw_name); $total_names++; } for(my $i=0;$i<length(@valid_names);$i++){ check_name($valid_names[$i],$i); } sub check_names{ my($name,$id) = @_; if($id == $total_valid_names){ say "$name is the last name! ($idth)"; } }
