  I propose a change instead of a removal,

  ref ($proto) || $proto;

  should be changed to:

  ref ($class) || $class;

  This would keep it in a OOP wording and possibly make it more essential for Perl-OOP beginners to understand what is going on.
  
  The construct is quite essential (I personally always use it).
  
  If you use inheritance, the result of not using could be strange since many people would perhaps not understand why their inheritance does not work and errors, which might be quite difficult to debug will occur

    Unfortunately this is a classic example of not understanding it - just copying it.
    
    This has nothing to do with inheritance or the two arg form of bless. It only has to do with being able to call ->new() on an instance of the class, and whether or not that's a good idea.
    
    Most people will never ever do this (as what they really want is a copy constructor, not a "call new on the object" method). I agree that all of these should be removed from the docs forthwith, but not just the docs, I think they should b

      Ok, now I read the docs on bless and AFAIK I can see I copied something without clearly understanding it - WHOOPS!
      
      Well the recommended syntax mentioned in the documentation should perhaps read:

      bless ... , (ref class);

      Instead of:

      bless ... , (ref class) || $class;

      It is custom to buy a kvajebajer in Denmark if you make an obvious mistake like this, so Matts or bart if I meet you some point remind me that I owe you a beer.
      
      And perhaps an excuse to MJD for not paying attention :)

        Sorry,
        
        The recommended construct should of course read:

        bless ... , $class;

        Hence the ref and || are the elements, which should be removed.
