This is a very valid, but a very rare use case. My point above is that whenever you use tuples you open a class of problems about "magic location". So you have to use them very sparingly with a lot of consciousness.

Here you also demonstrate that it is highly unlikely that const { data: customerError, error: customers } = useAsync(getCustomers) would happen, since it would look odd and you will not fail it.

Lastly in the example above, why don't use transform data inside getCustomers already so it returns {customers, customerError} instead? What if you realize you need to return more than two objects?

So, my point is: use it very rarely and very carefully.
