Hard disagree that julai perfected arrays. I love Julia but even compared with old with old “array programming lenguaje” like APL not even mentioning newer ones like BQN. Julia array still seem a less expressive than one might hope. There’s also an under explored area of compile time Shape checking, that might open up a new era in array. There has been interesting advancements in the Rust space like https://github.com/JErnestoMtz/rapl or https://github.com/chelsea0x3b/dfdx
