I wish asyncio had a `group()` function, see the snippet. Basically a version of `gather()` that uses a TaskGroup under the hood. Clear cancellation strategy when things go wrong and exception groups. Example: `r1, r2 = await group(thing1(), thing2())` Should I?

For the neophytes, what would the benefit of that approach over the simple gather() would be?

gather() should be "soft deprecated" because of bad cancellation behavior and lack of exception groups (making it unergonomic to catch errors from it)

If I’m correct, the difference between gather and group api is a better exception handle? Correct me plz if I’m wrong
