Continuation passing monads form the basis of a perfectly valid and usable software architecture and programming pattern.
In the case of ostream and operator<<, this pattern reduces the number of intermediate objects that would otherwise be constructed.
If you object to iostream on religious or stylistic grounds, there's always fmt which is more like Go or Python string interpolation.[0]

Project mention: Tracy: A real time frame and sampling profiler for games and other applications | news.ycombinator.com | 2024-05-12
If CPU/GPU execution speed is the goal while simultaneously code golfing the source size, https://halide-lang.org/ might have come in handy.

If you are talking about non-small matrix multiplication in MKL, is now in opensource as a part of oneDNN. It literally has exactly the same code, as in MKL (you can see this by inspecting constants or doing high-precision benchmarks).
For small matmul there is libxsmm. It may take tremendous efforts make something faster than oneDNN and libxsmm, as jit-based approach of https://github.com/oneapi-src/oneDNN/blob/main/src/gpu/jit/g... is too flexible: if someone finds a better sequence, oneDNN can reuse it without major change of design.
But MKL is not limited to matmul, I understand it...
You might also consider building some support for tracing and profiling directly into your engine using Tracy or easy_profiler.
Project mention: DwarFS – The Deduplicating Warp-Speed Advanced Read-Only File System | news.ycombinator.com | 2024-04-11https://github.com/mhx/dwarfs/blob/main/doc/mkdwarfs.md#nils...
Aside from that, there is a Python translation of data.table (see documentation here), which might be worth looking into. However, it hasn't had any major updates in a while: the last release 2 years ago ...

can_ada is just the python bindings, largely generated via pybind11.
The actual project is at https://github.com/ada-url/ada
