[$] Zig's new plan for asynchronous programs

The designers of the

Zig programming language have been working to find a
suitable design for asynchronous code for some time.
Zig is a carefully minimalist language, and its

initial design for
asynchronous I/O did not fit well with its other
features. Now, the project has

announced (in a Zig SHOWTIME video) a new approach to asynchronous I/O that
promises to solve the

function coloring problem, and allows writing code that will execute
correctly using either synchronous or asynchronous I/O.
