I agree that async/await has to eventually be added to D. I'm
not convinced it can or should be done with AST macros.
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.
