Subject: [ruby-talk:25178] Parallel array iteration

Hi

I've got a block here...It seems that I have seen that
Ruby can do iteration over multiple arrays, but I have
not been able to find it. For example, I would like
to do something like the following:

a=%w{a b c}
b=[1,2,3]

for x,y in a,b
 puts "#{x},#{y}"
end

a,1
b,2
c,3


Or even better yet, do the above without the 'for'.
Yes, I can do this with each_index, but I would like to avoid
de-indexing if I don't have to.

Thanks
