[ruby-core:62806] [ruby-trunk - Feature #9867] Introduce each/else block into ruby

Issue #9867 has been updated by Rodrigo Rosenfeld Rosas.


I'm curious. Personally I don't remember any time I used something like thi=
s. Would you mind showing some examples where it happens in your applicatio=
n?

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?
