Your simple code is being executed in the context of some private Object 
instance.

$ irb
irb(main):001:0> self.class
=> Object
irb(main):002:0>

Object class includes Kernel module which in turn defines all these 
puts, print, etc. methods. Your x variable is the local variable. All 
methods defined at the top level context become private methods of this 
private Object.
