Since (..., An, ... A2, A1, A0, L0) does not appear to be a list, why should there be any antidiagonal for it?
On the other hand, if (A0, A1, A2, ...) is a list of reals, then it will have an antidiagonal.

Outside of WM's world a recursive construction such as he suggests does allow an anti-diagonal to any list infinite anti-diagonals.
