As far as decimal.py in particular goes, there are significant maintenance gains in keeping a lot of the non-performance critical context management code in pure Python. So we're likely to wait and see how much speed Mark can wring out of a simple C decimal coefficient object

No need to wait for this. :-) I don't really expect to get much speed gain at all in normal, low-precision (= precisions less than 100 digits, say) use. Even doubling the speed would be way too much to hope for here.

The only real gain from a decimal integer coefficient would be fixing the asymptotics for high-precision calculations.
