Do any compilers support std::execution::task yet?

The `std::execution::task` seems like exactly what I was hoping for, thanks a lot for bringing it to my attention! It wasn't on cppreference when I was looking through the std::execution page.


We can kill this thread here then, reading the proposal it seems to support the cancellation I was hoping to see.

Iit returns a result that you use with co_await in a coroutine whose
result is a std::execution::task.

You can also make your own promise types sender-aware by using
std::execution::with_awaitable_senders.
