The following code worked in version 1.6.2 but does not work in version
1.6.3. (ruby 1.6.3 (2001-03-19) [i386-cygwin]). Is this intended?

--BEGINING OF bug.rb--

class Test
	def initialize(&block)
		instance_eval(&block)
	end

	def command(p)
	end
end

t  est.new do
	command proc do |w|
	end
end

--END OF bug.rb--

Produces the following error:

bug.rb:12:in `proc': tried to create Proc object without a block
(ArgumentError)
	from bug.rb:12
	from bug.rb:11:in `instance_eval'
	from bug.rb:4:in `instance_eval'
	from bug.rb:4:in `initialize'
	from bug.rb:11:in `new'
	from bug.rb:11

If you change the proc block to the following it works:

t  est.new do
	command proc { |w|
	}
end
