Are they even equivalent? (Score:1)

That would require that you never have a concrete class inheriting from another concrete class, which feels like a very bad thing to bake in.
Of course, I don't know how those ::SUPERs get in there. It's possible they can only arise when the class is already known to be abstract; but that just makes the whole thing even more obscure.
So, the second :). I would probably want the is_abstract method to be a sprinkling of sub is_abstract { 1 } and { 0 }s rather than simply that expression, as well.
