Subject: [ruby-core:52524] [ruby-trunk - Feature #7882] Allow rescue/else/ensure in do..end


Issue #7882 has been updated by nobu (Nobuyoshi Nakada).


=begin
I remember I've seen the same proposal.

What do you think about {} block?

  foo {
    ...
  rescue
    ...
  }

seems odd to me a little.

Or improve (({do}))...(({end})) only?

Feature #7882: Allow rescue/else/ensure in do..end

=begin
The keywords (({rescue})), (({else})) and (({ensure})) can be used when defining methods like so:

  def foo
    #
  rescue
    #
  else
    #
  ensure
    #
  end

However when using a block delimited by do..end, you must use (({begin}))..(({end})) as well:

  foo do
    begin
      # ...
    rescue
      # ...
      # ...
    end
  end

It would be nice to be able to drop the extra (({begin}))..(({end})) and use (({rescue})), etc. clauses directly:

  foo do
    # ...
  rescue
    # ...
    # ...
  end

I cannot think of any ambiguities this syntax would cause, but please correct me if I am wrong.
