I agree entirely. From a Huffman-encoding viewpoint, I'd say doing shift @a to discard the first element of the array and doing $_ = shift @a to put that discarded element in $_ is a far better allocation of characters than () = shift @a for discarding and shift @a for storing in $_. Not to mention those empty LHS parens look odd to some folks.
