I tried this was cursor and it was taking awhile. 😢

Prompt: "Replace c10::irange with std::views::iota"

It looks like it was searching for the c10::irange function definition to do an intelligent replace. Probably should add pytorch/c10/util/irange.h to the context.

I also tried asking for a simple string match replace and it defaulted to its original approach.

[rdspring1]

iota expects the types for both integer arguments to match. This is kinda annoying for the human or AI agent.
