Just for some context, it would be relatively straightforward to synthesize an init per class, but I don't know of a way to make Pyright aware of it. I'm not sure if you've come across it, but we've also implemented a rudimentary way to import IRDL in Python directly, as if it were defined in Python. We generate type stubs for Pyright, which is where such an auto-generated constructor could be typed. I do see people routinely write bugs in the op inits, it would be quite nice to have a better mechanism to do some checks here.
