Subject: to which object does the global scope belong?

x = RubyNG.each {|user| user.hello }.find {|user| user.knows_answer? }

=> #<X:0x401bcbf0>
irb(main):017:0> x.foobar
=> "foobar"
irb(main):018:0>

I was wondering in what object scope is the function foobar
defined?
I supposed it would be in

irb(main):037:0> Kernel.singleton_methods.grep /foo/
=> []
irb(main):038:0> Object.singleton_methods.grep /foo/
=> []
irb(main):039:0>

but nothing


x.each {|user| user.thanks }
;)
