Subject: each with else

Hi all,

that's just an idea I came up with and thought worth a discussion.

Would it be possible to give each an else part?

For Rails programmers it is very common to do something like this:

In controller search for records:

@orders = Order. find(:all)

In view:

<% unless @orders.empty? then %>
  <%   @orders.each do |order| %>
    <%= output order somehow %>
  <% end %>
<% else %>
  output message, that there are no orders
<% end %>

If each would have it's own else which runs if the
used array, enumerable or whatever is empty,
that code could look much nicer:

<% @orders.each do |order| %>
    <%= output order somehow %>
<% else %>
  output message, that there are no orders
<% end %>

I guess, that would be true for any other Ruby code, too.

Please give your opinions to that idea and if you think
there would be a chance to get this implemented one day...
