toolchain. Among other features it provides
@itemize
@item an Optional type instead of null pointers,
@item manual memory management,
@item generic data structures and functions,
@item compile-time reflection and compile-time code execution,
@item integration with C using zig as a C compiler, and
@item concurrency via async functions.
