However, everything is an instance of a class or type. And once old-style
classes are dropped, all classes will be user-defined types and types will
be built-in classes. And it seems that for instances of such unified
type-classes, type(x) == x.__class__:
>>> class c(object): pass
>>> c1 = c()
# don't know if user metaclasses can change this or not
So the distinction, if kept, will be pretty thin.
