So that TO is trying to "well order" his set of digit positions in some
weird way?

His difficulty will be how to deal with a that the "carry" operation
that carries out of the neighborhood of one of his "limit" digital
points and into the neighbor hood of another.

For instance, given any one of these "limit" digital points, how does
one determine what the next one will be? There has to be a next one,
doesn't there?

And the indexing within each neighborhood will have to correspond to
being indexed by the set of all finite integers, 0 at the "imit"
position, positive for more significant and negative for less.

And here is always the vexing problem of how does the transition from
one such "neighborhood" to the next work?
