I don't think shift is bad. I find myself using it in a lot of code, especially modules that I write for office use. In some subroutines, I find myself using 3-5 shifts. In one of my modules (Student::Server), I've done this:
sub usr_create { my $DC; Win32::NetAdmin::GetAnyDomainController('','CLC', $DC); my $obj = shift; my $usr_log_file = shift; my $params = shift; if ( $obj->usr_log($usr_log_file,$params) ) { return 0; } my $usr = $obj->_rand_user(); if ( not Win32::NetAdmin::UsersExist($DC,$usr) ) { $obj->usr_add($usr); } else { $obj->usr_create($usr_log_file,$params); } }
Most people would probably frown upon that usage, but I like it. If I only need one parameter (per variable), then it's much easier to avoid confusion about parameters. In the above sub, I expect an object, a filename, and an array ref (which contains the order of logging parameters). In other words, a call to usr_create would look like: $obj->usr_create('test.txt', [Last_Name, First_Name, State]); or even  $obj->usr_create('test.txt', $aref); shift'ing out the necessary parameters avoids silly things like having a user pass too many arguments to the sub. In that case, anything not shift'ed out is discarded.
