Someone who wants to pursue this, and likes the motivation
of a change to improve on the timbot, might consider a
Pythonic implementation of so-called "adaptive integers"
<URL: http://wiki.tcl.tk/4329 >.  For a useful range of
data, these occupy *less* space than "normal" computer-
encoded numbers, and exhibit precision limited only by
available memory.

The URL above gives the most straightforward implementation.
Myself, I like a variant which encodes rational arithmetic ...
