Right. And as such, it shouldn't stop with digit 9, but continue into
digits a, b, c, and so on, as appropriate.

Notice that it also supports bases other than 10:


So calling it "decimal" is a misnomer.

The hex codec doesn't have to do anything with number conversions;
nor does it have to do with character encodings. To introduce it was
a mistake in Python 2.x which has been fixed in 3.x (by removing
it and other similar "codecs", such as rot13).
