You are correct if `noUncheckedIndexedAccess` is enabled. It is off by default (which is a pity, really).

I assumed `Return<User>` was a mistake, not a custom type as you suggest. But your interpretation seems more likely anyway.

Both score 7 now though.

This scores 6: function a(b) { return b[0]; }

This scores 3: const a = (a) => a;
