If it isn't, then how do you start multiple tasks in parallel?
async def get_thing(id):
await spam(id)
await ham(id)
return await internet()
needed_things = [53, 110, 587]
tasks = [get_thing(id) for id in needed_things]
# ... now what?
Somehow you need to have three tasks run concurrently, and if you
weren't allowed to create an awaitable without immediately awaiting
it, how would you do that?
