 When you write this, you have defined 2 methods Test#a and Test#a=
 This is _like_ if you have written (in reality ruby has optimization for
 this case)

   class Test
      def a
         @a
      end
      def a=(b)
         @a = b
      end
   end


M> irb(main):023:0> t.send("a")

 Here you try to call the method #a for the `t' object

M> irb(main):008:0> send("$_" + x)
M> NameError: undefined method `$_foobar' for #<Object:0x2a79618>
M>         from (irb):8:in `send'
M>         from (irb):8

 Well you try to call the method $_foobar which is not defined
