I think we're getting to the stage where an updated text would be useful.

Yes, I plan to work on this over the weekend. Stay tuned!

For that, you may want to consider an actual implementation of, e.g., a very simple function like np.reshape as well as a more complicated one like np.concatenate

Yes, I agree that actual implementation (in Python rather than C for now) would be useful.

and in particular how the implementation finds out where its own instances are located.

I think we've discussed this before, but I don't think this is feasible to solve in general given the diversity of wrapped APIs. If you want to find the arguments in which a class' own instances appear, you will need to do that in your overloaded function.

That said, if merely pulling out the flat list of arguments that are checked for and/or implement array_function would be enough, we can probably figure out a way to expose that information. -------------- next part -------------- An HTML attachment was scrubbed...
