Does anyone know, in the new Swift async/await stuff, is there any difference between TaskGroup async and spawn, or are they pure synonyms? (If they are synonyms, I rather like spawn better. async looks like we're opening an async block, and that's not what we're doing at all.)

SE-0304, tells us that spawn was renamed async as part of the second review:
TaskGroup.spawnandTaskGroup.spawnUnlessCancelledhave been renamed toTaskGroup.asyncandTaskGroup.asyncUnlessCancelledwhich are to be their final names. This aligns the naming with the renamedasync letas the word signifying creation of a child task.
The portion in italics has subsequently been removed and the third review has renamed it again:
- renamed
TaskGroup.asyncandTaskGroup.asyncUnlessCancelledtoTaskGroup.addTaskandTaskGroup.addTaskUnlessCancelled. The fundamental behavior here is that we're adding a task to the group. add by itself does not suffice, because we aren't adding a value (accessible vianext()), we are adding a task whose value will be accessible vianext(). It also parallels the use ofTask { ... }to create top-level tasks.
