Yeah, see MADescription in the #validating protocol. To check if all
you objects are valid you can do:
anOrderedCollection allSatisfy: [ :ea | ea description isSatisfiedBy: ea ]
To validate your all your objects and trigger an exception in case of
a problem you can do:
anOrderedCollection do: [ :ea | ea description validate: ea ]
