Yao is already fully designed. And while I haven't updated its example file [1] to include everything, it would only be a max of two or three times bigger.
This includes generics, an equivalent to Zig comptime, something like traits but more powerful, a solution to the expression problem, etc.
The solution is structured concurrency.
The only reason I am not working more on Yao is because I worked on it for three years at full tilt (because I constantly refactor to eliminate tech debt), and I am burned out.
But adding a new feature takes only about two hours max; I just add a new client-defined keyword.
There's a smaller, simpler, safer language lying in Rust called "Rust without async", which would be good enough for the 99% of use-cases that don't need absolute-lowest-possible-latency async.
