Subject: [ruby-core:53084] [ruby-trunk - Feature #7994][Rejected] Make iterators pass an implicit named parameter `iteration` to the executed block


Issue #7994 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Rejected

Nice idea.

But I reject the idea for Ruby for two reasons:

* I personally don't like implicit parameters
* That might cause incompatibility by conflicting with existing local variable name

Maybe good for a new language without existing set of programs.

I think it would be nice to be able to write something like this:

  items.each do |item|
    unless iteration.first?
      # do something that is not applicable to the first iteration
    end
    # do whatever is to be done to all items
  end
=end
