 mio5_utils.pyx:412:10: Only final types can have final Python (def/cpdef)
 With Cython 0.16 there's no problem. The explanation by bfroehle on the PR
 It isn't possible to have an inline'd def or cpdef method, as
 otherwise you'd get conflicting results depending on whether you
 called the method from C or Python if a subclass overrode the method.
