Seems like a reasonable addition by extending our PyCode type.

I'd be interested in working on this if it hasn't been picked up yet. Could you explain more about extending PyCode?

I'm also curious if the following could be a possible approach:

(1) Create 2 new methods:

pub fn compile_code_string(self, code_str: &CStr, start: c_int) -> Bound<'py, PyCode> {...}
pub fn run_code_object(self, code_obj: &Bound<'py, PyCode>, globals: Option<&Bound<'py, PyDict>>, locals: Option<&Bound<'py, PyDict>>) -> PyResult<Bound<'py, PyAny>> {...}

(2) Modify run_code so that it calls compile_code_string followed by run_code_object.

(3) Document the methods as part of the public API.

I'm still new to the codebase, so this is just an initial thought.

Yeah something like that. I'd just call them compile and run though.
