Subject: [ruby-core:62798] [ruby-trunk - Feature #9867] Introduce each/else	block into ruby

Issue #9867 has been updated by Yukihiro Matsumoto.


We have to define as a whole. If we have introduced your proposal, what should the semantics of a block be?
Or how we could invoke else part when we define our own each-like method?

Matz.

Hi

Code like this happens quite often:

    if array.any?
      array.each do |elem|
        some_work
      end
    else
      do_something_else
    end

I was thinking if it was possible, to introduce syntax like this:

    array.each do |elem|
      some_work
    else
      do_something_else
    end

where code in else would fire if array is empty. This would simplify a lot of code nicely and would be completely backwards compatible. Is that a good idea?
