If it is supported, it could perhaps be handled by allowing
the return type of the __new__ method to be declared explicitly,
defaulting to the class. E.g. given
cdef class Foo:
def __new__(cls, ..):
...
then Foo() is assumed to return something of type Foo, but
given
cdef class Blarg:
def object __new__(cls, ..):
...
then Blarg() could return any type of object.
