[$] Zig explores structured concurrency

Version 0.16.0 of the Zig programming language was

recently announced, and with
it an expanded version of the new Io interface that we

covered in December.
The new interface is based on an idea called structured concurrency that makes writing
correct concurrent applications easier. Zig’s implementation of
the idea is more explicit and verbose than other languages, however, which could
offer an opportunity to explore the consequences of different designs.
