Precisely!

is really assignment operator definition and not a normal message, 
method or a function if you like. Take away the equal sign and it will 
behave like you'd expect it. This does not mean that there is no bug 
here, however, it is highly unlikely that anyone who uses the assignment 
definition properly would ever see it. The bug showed up in a slightly 
incorrect use of this feature and I do believe should be fixed if for 
nothing else but for the sake of completeness, when all far more serious 
bugs are fixed ;)

  |  class MyTest         |
  |    def nothing(data)  |
  |      return false     |
  |    end                |
  |  end                  |
  |  o = MyTest.new       |
  |  puts o.nothing=(123) |

  |OUTPUTS: false         |
