Meta operators (II)

• If you do need to sum the elements of two infinite lazy lists, you can use the zip meta operator
• Instead of @a »+« @b, you can do @a Z+ @b
• Z+ evaluates the lists lazily and returns its values lazily
• It's effectively doing (@a Z @b).map(* + *)
• <a b c> Z~ <1 2 3> returns a1 b2 c3
• Likewise, the cross operator X has a meta operator equivalent
• <a b c> X~ <1 2 3> returns a1 a2 a3 b1 b2 b3 c1 c2 c3
