## Context I am trying to wrap a few Rust objects in a Python API - basically an enum of a few different types. ```rust enum Things { Obj1(String), Obj2(f64),...
### Bug Description When trying to build optional arguments, using `from_py_with` I'm getting ``` expected struct `InnerType`, found enum `Option` ``` ### Steps to Reproduce ```rs fn build_regex(obj: &PyAny) ->...
In comment to `Py::as_bytes`: ---- I think there's a few other immutable types like `str` and `tuple` which I guess can also have treatment like this where `py` is necessary...
