Subject: [ruby-core:27661] [Bug #2623] drb - circular require

Bug #2623: drb - circular require
http://redmine.ruby-lang.org/issues/show/2623

Author: Benoit Daloze
Status: Open, Priority: Low
Category: lib, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2010-01-14 trunk 26319) [x86_64-darwin10.2.0]

Some gems(for example rspec) require drb:
require "drb/drb" # It should probably be just "require 'drb'", but it's the same anyway.

/usr/local/lib/ruby/1.9.1/drb/eq.rb:1: warning: loading in progress, circular require considered harmful - /usr/local/lib/ruby/1.9.1/drb/drb.rb
	...
	from /usr/local/lib/ruby/gems/1.9.1/gems/rspec-1.3.0/lib/spec.rb:6:in `<top (required)>'
	from /usr/local/lib/ruby/gems/1.9.1/gems/rspec-1.3.0/lib/spec.rb:6:in `require'

	from /usr/local/lib/ruby/gems/1.9.1/gems/rspec-1.3.0/lib/spec/runner/drb_command_line.rb:1:in `require'
	from /usr/local/lib/ruby/1.9.1/drb/drb.rb:57:in `<top (required)>'
	from /usr/local/lib/ruby/1.9.1/drb/drb.rb:57:in `require'
	from /usr/local/lib/ruby/1.9.1/drb/eq.rb:1:in `<top (required)>'
	from /usr/local/lib/ruby/1.9.1/drb/eq.rb:1:in `require'

This is due to drb/eq.rb, with this line:
require 'drb/drb'
That seems useless to me. You will never require this file directly, as it just allow to compare DRBObject.

So, shouldn't that line be removed ?
