Question about attrbutes and C++20 coroutines #108730

Open kelbon opened 1 month ago

kelbon commented 1 month ago

As i understand, now all attributes like [[pure]] [[always_inline]] [[flatten]] [[cold]] [[hot]] etc when applied to coroutine function applied to implicit function which return coroutine, not to coroutine itself

So, my question is how to, for example, apply [[flatten]] to coroutine::resume function? Is it possible?
