Well, if you do something like
ctypedef fused_type(float, double) speed_t
ctypedef fused_type(float, double) acceleration_t
cdef func(speed_t x, acceleration_t y)
then you get 4 specializations. Each new typedef gives a new
polymorphic type.
OTOH, with
ctypedef speed_t acceleration_t
I guess only 2 specializations.
Treating the typedefs in this way is slightly fishy of course. It may
hint that "ctypedef" is the wrong way to declare a fused type *shrug*.
To only get the "cross-versions" you'd need something like what you
wrote + Pauli's "paired"-suggestion.
This is a bloatware generator.
It might not be used right, or it might generate bloat due to small
mistakes (which will go unnoticed/silent).
