Out of curiousity, how would that be implemented without
macros? I could see it being done with macros with a rewrite
and using some of the standard library (like std.parallelism),
maybe. But with a language feature, you couldn't use the
standard library. It seems like some parallelism code would
have to leak into the runtime to get it to work as people might
expect.
I guess I would have thought the exact opposite from you...
that this is precisely something that *should* be done with a
library-defined macro.
async await do not create parallelism.
