Ah sure, this alternate implementation assumes that the BlogPost class is final and never subclassed.

If you plan to subclass BlogPost, the translation is not identical, as the alternate implementation would not keep track of a global count of posts across all subclasses, only of `BlogPost` instances exactly.

I saw you closed my ticket on sorbet for generics + sealed + exhaustiveness, that’ll allow some very welcome code cleanup!
