Is it definitely a variable, not a method?

This post shows how to start an IRb session within the context of an 
arbitary object:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/244139

So you can create your own object class with a "client" method, create 
an instance of this object, and start IRb such that "self" is this 
object.
