Well, its not like the person is getting Y when he is expecting X.  
Both classes have the same name after all, so there is some relation  
between these two classes. More importantly its the users choice to  
enable this in __autoload(). As all frameworks got that its the end  
users job to implement autoload, I would not worry soo much in this  
case.

Just a question: How hard would it be to implement in case we do want  
this?
