Sure; if we go with the "cofunction" names, there's no conflict; if we go with the "coroutine" names, there is, although it may be easily avoidable. So that counts as a point in favor of the former.

In the other direction, while don't think (although some people in this thread obviously disagree) there's anything inherently confusing about "cofunction", or anything inherently intuitive about "awaitable coroutine", the fact that F# used the latter terminology, and a number of well-known languages have copied it and heavily encouraged its use, definitely makes a difference.

Anyway, since the difference is (as you pointed out) ultimately just about names (and maybe some minor details of which features go into the first version and which get added later), I think the opinions of to the people who will be teaching and/or evangelizing the feature are so much more useful than mine that I don't have any more to say.
