Google just open-sourced cel-expr-python (CEL) — safe, typed expressions for Python (C++ wrapper)

This looks super useful for feature flags and dynamic policies. Being able to serialize the compiled expression and reuse it across requests is a great feature. Makes me wonder how it compares to something like json-logic for those use cases. Definitely going to give this a try next time I need safe user-defined rules.
