Description
pybind11 talks of course about how to wrap C++ classes so that they are accessible in python. The issue for me is that on the python side of things, we are using dataclasses very extensively. They provide a lot of useful built in features as well as type annotations that you can use with mypy. If you are wrapping a C++ class, then obviously, all the types are already present, so in principle it would be possible at no extra cost to export a dataclass rather than a regular python class, which would be really useful.
Maybe this is not possible to do from a purely C/C++ module, but if it is it would be pretty amazing.
