Ref counts have cycles, which cause leaks (in this universe). But I digress. Overhead like increments only matters on hot paths, which are very few. The Python + C stack for ML is a manifestation of this truth. Having ergonomics of a “regular language” (affects all code) and the ability to optimize for performance (hot paths only) and stay in the same language is what I’m excited about.
