Amend Rule 2337 (Promises) by appending:
A persistent promise is one whose conditions for destruction on
cashing is {false}. A revocable promise is one whose set of
conditions for author destruction is {true}.
The rest of that rule is phrased for the condition to go the other way:
condition for the promise not to be destroyed when cashed.
(Nobody seems to use this condition, I couldn't find an example in
Horton's report. So I don't even know what it's usually called.)
