What I want to push is a 'mathematically sound' numeric prelude. A proper numerical prelude should have bona fide mathematical obects like groups, rings, and fields underlying common numerical classes.
Why not Clifford algebra: to simplify mathematical physics, mechanics, computer vision, improve neural networks etc.? That would probably be easier with OCaml-style categorical machine architecture. But then why not go for combinatorial stuff like matroids or graphs? More mathematics in a programming language won't harm general applications written in it. On the contrary, almost any human endeavor could be mathematically structured and thus programmed. Present languages are office-oriented for lack of mathematical knowledge and not any hidden virtue.
