Please do that work for me, if you like to have such a list. I told
you already that I appended every definable tail.
But your idea of listing is not very usefu in this context. Consider
the list of all Cantor-lists that are possible (i.e., definable) and
append all anti-diagonals that are possible (i.e., definable), then
you get a list that cannot be diagonalized because it contains its
anti-diagonal already. And if you would try to diagonlize the
countable union of all this countable stuff you must fail, because
this stuff already contains all anti-diagonals of infinitely many
steps - and more are not feasible.
There remain two possibilities:
Either there is no list of all lists including all their anti-
diagonals. This case is tantamount to there being not all steps to
Or there is this countable list containing all its antidiagonals. Then
Cantor's argument fails because this list cannot be diagonalized.
In both cases there is nothing uncountable.

So where and in which form *exist* all reals?
