Hmm, after writing up that list, the idea of using "\_\_cause\_\_ is

Ellipsis" (or even "\_\_cause\_\_ is ...")to mean "use \_\_context\_\_
instead" occurs to me. After all, "..." has the right connotations of
"fill this in from somewhere else", and since we really just want a
known sentinel object that isn't None and isn't a meaningful type like
the boolean singletons...
