The classes body applies to all promise types, including class promises, right?
I wonder what happens if you just specify a persist_time attribute in a
classes compound body, and use that in a class promise? :)
So I tried with this little bit of demo code, and it does't appear that the
classes attribute is actually used for a class promise. :/ I'd think that
specifying a persist_time ( perhaps with a promise_kept => "$(this.promiser)" )
would be the way this should work. But it seemingly does not work that way.
