Original Summary

I forked CPython to experiment with adding optional chaining (?.) directly to the language.<p>For example: name = response?.customer?.name.lower()<p>If response or customer is None, the expression short-circuits and evaluates to None. This isn&#x27;t a library or a transpiler change, but a direct CPython modification.<p>A bit about the build: I used AI extensively for this experiment. Part of my motivation was to see how far I can get the modification in an unfamiliar codebase like CPython.<p>A couple of hours in I had a working prototype. I would appreciate feedback from people familiar with CPython internals about the implementation.<p>Source: <a href="https:&#x2F;&#x2F;github.com&#x2F;grandimam&#x2F;cpython" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;grandimam&#x2F;cpython</a>
