That contention (above) may have been taken slightly out-of-context.

Referring back to the previous contribution: mutating a list-element is
not legal, because just like an object's attribute addressed with
dotted-notation, a subscripted object is not regarded as an identifier.
Whereas creating a (whole) new list (for example) IS legal, because the
list's name IS an identifier.

Yes, the LHS must be an identifier - the point that was made in the
first response (quoting "Python Language Reference") and since.
