Without answering your specific questions, keep in mind that Python and Python-C code are very different things. The current Decimal implementation was designed to be readable and efficient Python code. For a look at what the Python-C implementation of Decimal might look closer to, take a look at the Python long implementation.

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.
