zip uses a prototype so you can do 

zip(@a1, @a2, @a3)

[download]

What's actually passed to zip is a reference to each to those arrays. By overriding the prototype, you can pass those references yourself. 

&zip(\@a1, \@a2, \@a3)

So next, we need to build a list of the reference. Why are you using a hash for ordered data?! 

&zip map $hoa->{"obj$_"}, 1..keys(%$hoa)
