Yes, I must remember that what you give a definition it can't be taken to define all cases. It seems that "to list" is used as stated, but also for finite sets and, quite probably, probably for others as well. I doubt it has any meaning at all. In English, a listing is a bijection with N. You don't see able to say what "a listing" means in WMglish.

Why do you keep editing my words without any indication (this time mid sentence!)? It's deceitful, and in this case there was a typo in what I wrote, so there was no need to edit me at all. Let me put it this way: if we accept your (minor) abuse of notation and describe unending sequences that can be finitely defined as having finite KC, and unending sequences that can not be finitely defined as having "infinite KC", then you are stating that there can be no finite description of the list of all reals (because at least one, according to you, has infinite KC) but there is for the list of all rationals (take the S I defined, for example  it is an effective procedure for generating the positive rationals one by one).
Of course, this should surprise no one, since it's standard mathematics, and all of your mathematics is standard mathematics. You just lob in a few word bombs in WMglish to get an argument going.
 Ben.
