Subject: How to change the owner of a method in a block?

Hi, let me explain with this simple code:

--------------------
class A

	def initialize(&blk)
		blk.call
	end

	def hello
		puts "HELLO !!!"
	end

end

a=A.new { hello() }

=> block_1.rb:13: undefined method `hello' for main:Object (NoMethodError)
        from block_1.rb:4:in `call'
        from block_1.rb:4:in `initialize'
        from block_1.rb:13:in `new'
        from block_1.rb:13
---------------------------------


I understand perfectly what occurs: When passing "hello()" in a block,
it's like if the current object is "main:Object", for which there is
no "hello" method (of course).

Well, I'd like that "hello()" would be runned as class A instance
method. Is it possible is some ellegant way?

Thanks a lot.
