Ack, you're right about what you noticed about line 5. I goofed. You're also right about the defined test.

The only caveat i can think of is that if the $arrayref got set to an empty arrayref, i'd still not want to do the if conditional (in this situation). So i think the final will be: 

   if ( $arrayref && @$arrayref ) {

which will throw an exception if its not an arrayref.
I use the most powerful debugger available: print!
