Description

As of now it's not possible to decorate Python classes defined in Rust using a decorator defined in Python.

@davidhewitt proposed implementing a new argument for pyclass so that a struct can be defined with #[pyclass(decorate_with = "some_decorator_function")].

Research direction

No files, tests, or entry points are named. Start by locating the pyclass macro implementation and its existing argument handling, then determine how a Python decorator can be applied to Rust-defined classes; done means supporting #[pyclass(decorate_with = "some_decorator_function")] with coverage for the requested behavior.
