The Chang'e 8 mission, in addition to scientific surveys and experiments, will test key technologies to lay the groundwork for the construction of a science and research base on the moon, Xinhua reported.

For potential settlement, the lunar poles offer the most moderate temperature range." -------------------- "The Earth is a very small stage in a vast cosmic arena"

There's already some small amount of heat, since the rims of even deep craters will experience full sunlight, and that reflects down into the shadowed regions. I recall a paper comparing the polar craters of Mercury, the Moon, and Ceres, and obviously the effect is worst at Mercury. Anything directly exposed at the surface would have sublimated long ago, but since much of the volatiles are buried some distance under the regolith (much like Phoenix encountered when scooping with its shovel), the vast majority should be well insulated.
