No, the "mcl" in the call is just the designated metaclass - the

I'm not completely sold on adding a class method to type, but I acknowledge
that it's a convenient place to put it. Still, it doesn't feel particularly
more right than adding it to say, the operator module.
The operator module strikes me as completely wrong. To me, a function
that creates classes (types) belongs either in the types module or
attached to the type metaclass. Attaching an alternate constructor to
type as a class method would be analogous to attaching an alternate dict
constructor to dict (.fromkeys).
