TypeScript 4.6.2 supports Array.prototype.at, unfortunately its behavior is not consistent with array[number], see microsoft/TypeScript#47660
I propose a strongly-typed version of Array.prototype.at, at least support -1 on tuple.

Maybe the method name should be changed to tupleAt?

Would it only have stronger type for tuples?

Yes as far as I know.

This is "pull request welcome", but must be implemented in sindresorhus/type-fest#369 first.
