[Israel.pm] Correct way of taking a slice of a hash reference

Hi,



What is the correct way / best practice of taking a slice of a hash reference:

        @{$hash_ref}{ @keys };

Or:   @$hash_ref{ @keys };



Using @$hash_ref{ @keys } I get a "@$hash_ref Not an ARRAY reference" warning in Komodo

however I get no warning when running the same code with use strict and use warnings 

in the Perl debugger.



Am I missing something?

Thanks,

Adam.
