zig
General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.
Rust was originally built with green threads. The RFC that proposed removing them has an extremely detailed explanation of why the change was made pre-1.0: https://github.com/rust-lang/rfcs/blob/0806be4f282144cfcd55b...
I think this has proven itself to be the right decision. It's one of the main reasons that Rust works so well alongside other languages—there's very little default Rust runtime that complicates interop. There are also lots of programming scenarios for which green threads are not the right tool, and Rust accommodates those.
I tend to agree that allocator param isn't that strong of an argument (e.g. one can easily just store a pointer to the allocator in a struct to hide it from method signatures). And it is quite valid to just create a local allocator and `defer a.free(thing)` to clean up at the end of a function (for example, if you just need a trivial std.mem.join and you know that you can fit the result in stack). One does not need to use the top-level GPA/arena for everything.
But nonetheless I think there is a split (at least for now). Zig async function frames are different than regular functions, so even if syntactically, `foo()` could magically be switched between sync or async based on io_mode, in practice if you have a recursive call tree doing fs operations, it'll work in one mode (up until a stack overflow, that is) and throw a compile error upfront in the other. Presumably this would not be an issue anymore once [0] is implemented.
