Two years ago there was a split of fiber.d in commit b13c0cd . This has rendered the documentation https://dlang.org/library/core/thread/fiber.htm useless as a) the example has vanished, b) the function references have vanished. For reference here's a link to an old version which was decently usable: https://docarchives.dlang.io/v2.110.0/phobos/core_thread_fiber.html
