Swift is getting async, structured concurrency and actors

[Jacob Carlborg]

As the title says, Swift is getting language support for: async/await 
[1], structured concurrency [2] and actors [3]. The implementation has 
already started, available in master.

Seems like D is more or less the only language without language support 
for async/await now. But perhaps it's possible to implement only in 
library code. Kotlin has language support for coroutines, but 
async/await is implemented in library code. D already has fibers (kind 
of like coroutines) implemented in library code.
