Data descriptors on module objects. Let's suppose we have, say, a BCD
module. For example, we want to set the "global" rounding state on a
per-thread basis. By definition, modules are singletons, so there needs
to be a container within the module to hold the per-thread rounding
state. Question is, how/when do we update that container? Currently,
the only option is to require a user to call a function with the new
setting as a parameter; I can imagine cases where it would be convenient
to be able to simply set the module attribute, exactly the way we now
permit with new-style classes.
