in thread multiple local vars in a foreach loop

Right answer to wrong question! ;-)

DB<156> while (my ($key, $value) = each @a) { print "$key, $value" } +;; Type of arg 1 to each must be hash (not array dereference) at (eval 13 +5)[multi_perl5db.pl:644] line 2, near "@a) "

      each:

      it will also return the index and value for the next element of an array so that you can iterate over it;

      Wrong answer wrong question! ;-)
