Subject: Matz: can we have rescue/else/ensure available in all blocks?

Hi Matz,

I recently posted a Ruby 1.9 wishlist (http://groups.google.com/group/
ruby-talk-google/browse_thread/thread/d771ffa9fe10b811/
c8b5b0b02bd1e2d4) and the #1 item was to have rescue/else/ensure
available in all blocks w/o the need for begin/end.  It turned out to
be the one thing that everyone agreed on.  I think anyone who has done
a real project in Ruby has run into this.

Is there any way you can get this in 1.9?

This (contrived example):

pages.each do |page|
  page.links.each do |link|
    process link
  rescue MalformedLinkError
    @bad_links << link
  end
rescue MalformedPageError
  @bad_pages << page
end

Is so much nicer than this:

pages.each do |page|
  begin
    page.links.each do |link|
      begin
        process link
      rescue MalformedLinkError
        @bad_links << link
      end
    end
  rescue MalformedPageError
    @bad_pages << page
  end
end

It would make all our lives better!  :]
