t use the return result.

I have used Array#zip in hot-path code to avoid unused array
generation.  So I don't want it to generate a unused and big
array.  But this is just my personal opinion, not a decision.
If matz says ok, it is ok.

BTW, ko1 is now studying optimization to avoid unnecessary
object generation by using escape analysis.
If it is achieved, my concern will be pointless.
