IIRC, I ran across that using the "($hash{$key} || 0);" idea.

I'll try defining the new key one step at a time and see what that produces.

I know there's a few options that can be appended to the "use strict" line - which one will apply to this hash key issue? My Google search term MoJo isn't finding the information.
If you just want to turn warnings off the best you could get without re-coding the block
would be to add C<no warnings;> after line 55.
