"it's confusing that you have @wwn and $wwn."

Respectfully disagree: where an array is the child of a string (or vice versa), having both use the same base_name makes all the sense in the world to me... and from the original post, it's pretty clear that "wwn" is a meaningful name to the OP (ie, not a case of naming stuff $var1, $var2, @arr3, %h4 or the like, which, of course, would warrant advice to select meaninful names like $ip, $mac, @wwm... (sorry, no hash example in the OP).
