Er, perhaps I should have said explicitly that I was looking at the
Decimal-in-C code and not the Python.  Most of my questions don't
make any sense at the Python level.

But you have a good point.  The long code will be both simpler and
have had a LOT more work done on it - but it will address only the
object of variable size issue, as it doesn't need class-level data
in the same way as Decimal and I do.
