1. The example above only works when using a cached
memento. It fails due
to
DNU #cache for other Memento types, as well as when validating objects
directly (e.g. `myDomainObject magritteDescription validate: self.`)
This one was actually a bug/limitation in the example code. Replacing `cache
at:` with `readUsing:`, which is polymorphic among all Memento types and
Object, solves the problem.
So:
```
addCondition: [:memento |
(memento cache at: self descriptionEndDate) > (memento cache at:
self descriptionStartDate)]
```
becomes
```
addCondition: [:memento |
(memento readUsing: self descriptionEndDate) > (memento
readUsing:
self descriptionStartDate)]
```
