> For this to work you either need an ultra-sophisticated compiler what will transparently auto-async your code at compile time (as realistic as a unicorn at this point) or a heavy runtime which will have performance implications. Depends on how much of it you want to solve automatically. The Zig compiler does essentially auto-async your functions. So I think you can write a whole lot of synchronous code, and then just have a single "async" at the top to have it yield to the event loop whenever it hits blocking IO. So I think you can solve 90% of that problem without being ultra-sophisticated.
