In our project, I need to listen the events of module/class defined,  
and record the events that include the context of the module/class  
defined. In ruby, I cannot add a listener for the module/class  
defined, only i can set a proc with set\_trace\_func, in the proc, I  
cannot get the module/class name from the parameters.
