I disagree. It's not an uncommon to see the pattern:

  def foo
    o = Somthing.new
    # muckaround with o
    return o
  end

The #returning method provides the same kind of "block orientation" we
use with files.

  def foo
    returning Something.new do |o|
      # muckaround with o
    end
  end

In simple cases, sure, it's no dig deal. But in more complex cases it
lends to readability b/c it tells us what we're after from the start.
