Hi,

Take a look at the following example:

   class Symbol
    def []=(signature, body)
      nil
    end
   end

   def method(*args)
     p args
   end

   method(:empty['=> bool'] = 'return @size == 0')
   # => ["return @size == 0"]

I'd expect:

   [nil]

as I return "nil" from []= method call.
