It gives the below:

>> class Test
>> end
=> nil
>> foo = Test.ne
NoMethodError: undefined method `ne' for Test:Class
  from (irb):12
  from /usr/bin/irb:12:in `<main>'
>> foo = Test.new
=> #<Test:0x00000001cdd240>
>> bar = Test.new
=> #<Test:0x00000001cdfe50>
>> Hash[local_variables.map {|k| [k,eval(k.to_s)]}].inspect.scan(/(?:\{|
)\:([^=]+)\=/).flatten
=> ["bar"]

Not ["foo","bar"]
