My standard mathematics does not include any numerals for reals having
any digits in infinite places, just in infinitely many finite places,
like the decimal representation of 1/3 as infinitely many 3's each in a
finite place following the radix mark.

WM can, and often does, state anything he likes, but his stating things
does not make them true, and WM is somehow never able to provide proofs
valid outside his WMytheology of what he claims goes on in his
WMytheology unless it also goes on in what WM miscalls matheology but
everyone else calls standard mathematics.

And elsewhere, though it clearly it bugs WM that Cantor is right and WM
is wrong anywhere.
