[ruby-core:56451] Re: [ruby-trunk - Bug #8735][Open] Enumerator::Lazy#zip behaves differently from Enumerable#zip when yield with non-single argument

I believe the issue is here:
https://github.com/ruby/ruby/blob/trunk/enumerator.c#L1703

I'd write a patch for the cases argc==0{Qnil} or argc>1{rb_ary_new4(...)}
but I'm away from my computer right now.

Sent from my phone, so excuse the typos.
