I do not dispute this statement (as I erroneously had said yesterday,
when being in a hurry). I dispute that this statement implies the
statement:
d is not in one of all lines of the infinite list L and, hence, cannot
be used to argue that cardinality is increased.
(The reson is that "all" is maeningless here.)
What about C1, C2, C3?
