This is the way. And that pip command is just clean.

So basically Perl autovivification for Python?

This is more of a political statement than a proper library. More to demonstrate the flexibility of Python given I was able to so easily do this.

Have I lost my marbles? It doesn't work?

    (temp5)   ~/temp5 pip install .            
    ERROR: Directory '.' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.

Does it lazy-create leaf dicts on access? It would be preferable if they were only created on assignment, and failed if it’s just a get.

For example, if I call config.usors.adminn.naem I’d like it to fail loud and fast to point out the typos.

Run it from a clone of the repo to install it to the system / your user.

I don't see a name to install this from pypi (I see several dotdict libraries on there but they don't link here, so don't know if this is there somewhere).

Code looks like it's on access, but I didn't test it.

I don't think it's possible in Python to detect the difference between access or write (when it's nested attributes).
