Subject: Re: How each class splats

Well, you could do this:

class B < Array
  def initialize(i,v)
    self[0] = @i = i
    self[1] = @v = v
  end
end

But I think your best bet is define your own Collection object with its 
own #each.

Interesting sidenote (endnote?): Operator precedence causes this:
  self[0], self[1] = @i, @v = i, v
To set self[1] = @i, and @v = i, and to return the Array containing 
self[0], self[1], @v, and v. If you want to do a silly thing like chain 
parallel assignments, you have to add parens:
  self[0], self[1] = (@i, @v = i, v)
But then again, that's what you get for trying to write code that's 
painful to read.
