Therefore I said improper limit.
Not in what? Note that since you concede that it is Not A Number in "analysis" it need not have any digits in it and WM's whole argument now clearly fails. > > > > > an element of the extended reals. > > > > I've not studied the extended reals.

WM seemS to have been extremely interested in "how" it is called, since WM claimS that calling it at all NECESSARILY involves strings of digits. --
