It is definitely worth pointing out that this isn’t new, the idea itself is truely fascinating and the author clearly articulates this is code as art. It is definitely eye opening once you read into the details. I stumbled across this when a new chapter of crafting interpreters came out, and I ended up doing a deep dive into how to speed up CPython. My conclusion was that it wouldn’t be possible without rearchitecture of the fundamental types, and hence unpalatable, but a fun exercise none the lesser If you’d be wrong to so quick to dismiss Cello. Cello is an order of magnitude quicker than python, even cython can only achieve 3x on CPython without annotation. The ideas behind Cello put it somewhere around JavaScript speed, but far more extendable, and definitely worthy of further investigation. To expand further, fat pointers (void type, void data) could be superior to NaN boxing, and I’m not aware of any interpreted languages that have seriously implemented fat pointers, but it seems to be going well for Rust.
