Programmatically update Docstring

Hi,

I want to use Trace to build an application to let non-engineers optimized code for certain tasks. Ideally I would like to have an f-string in place of the docstring for a number of bundled functions that are methods on classes decorated by @model but of course python requires docstrings be a string literal. I'm REALLY trying to avoid resorting to a templating library for this. Currently I am trying to update the docstring of a number of bundled functions through some combination of bundled_function.description bundled_function.info['doc'] bundled_function._fun.__doc__ but so far no matter what I do I can't see the new docstring in the parameters of either the function node or in the associated optimizers.

Do you all have a suggestion of how I could implement a templated docstring? For reference here's a SUPER minimal example of what I mean:

@bundle some_func(input_data):
f"""input_data is {data_description}. 
You need to {task_description}. 
Make sure you don't {caveats_description}.
"""
    pass

Start by tracing how @bundle functions expose bundled_function.description, bundled_function.info['doc'], and bundled_function._fun.doc, then follow how function-node parameters and associated optimizers consume those values. Done would mean a supported way to provide templated docstrings whose rendered text appears in both the function node parameters and associated optimizers.
