Comment (by vbraun):
Another backend for immutable NetworkX graphs, another backend for
immutable dense graphs, another backend for immutable sparse graphs? Thats
crazy.
We could move the mutability stuff to the base `GenericGraphBackend` but
then we still have to push the actual check into each backend. Its a
possibility, but it does include quite a bit of copy&pasting. And you then
can't use the backend in some other code without the mutability check. I
think it would be cleaner to just encapsulate the backend (whatever it may
be), and push our implementation of mutability into `GenericGraph_pyx`.
I can produce a patch that switches the backends to Cython but we should
first be onboard that this is the way to go.
