Any D answer to C++20 coroutines?

Been out of the loop for a good while, but I've been very curious about one thing for a long time, so I thought I'd pop in and ask:

From what I can tell, it sounds like C++ now has stackless coroutines (ie, AIUI, a rough equivalent of both C's protothreads library and C#'s internal rewrites ["lowerings"] of coroutines). Now that C++ (apparently?) has it, does D finally have any take on it, beyond crickets?

C++20 has it, but it is somewhat low level in the current incarnation, waiting for library authors go get familiar with it. Libraries have to be built on top if it to make it easier for the end user. I think we can expect some of that to be included in C++23.

A tiny handful of people have expressed interest in it, but I am not aware of any work being done on this for D. All the focus seems to still be on "@safe", but with no willingness to change the language semantics. It is nice to know that giving D a reasonable memory management situation (without garbage collection) is part of the roadmap, but it is moving so slow that it is difficult to judge where it will end up, and when.

What D needs now is an explicit roadmap, without at roadmap everything that isn't already in the language gives the vibes of a Fata Morgana on the horizon.

A roadmap for fixing known language and runtime deficiencies would be a good starting point.
