It's only degenerate if you want a real world example, and not one that provides a simple answer to your original question... > A more telling example might be > > cdef double dot_product(floating *u, floating *v, int length) > > By your current rules, this would give you one version that > takes two float vectors, and another that takes two double > vectors. > > But if you want to find the dot product of a float vector and > a double vector, you're out of luck. Sure, so you can create two fused types. I do however somewhat like your proposal with the indexing in the definition. > -- > Greg > _______________________________________________ > cython-devel mailing list > cython-devel@python.org > http://mail.python.org/mailman/listinfo/cython-devel > _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
