Re: MOP question for language lawyers: can you specialize on standard-class

Yes, I don't see why not.  In fact, I think you have to specialize on the
class argument if you don't have a specific metaclass because otherwise the
AMOP method that specializes on standard-class (and doesn't specialize on
object) will be the most applicable method and your method will never be
called.

What are your concerns about it?
