From what I
could see it looks like a blank field will be interpreted as a
nil, which means
that the domain would need to check for nil in accessors
and return a default.
Another option which I tried is to rather change MAMemento>>push: to make
use of the #default: magritte description.
I.e. when creating your MAStringDescription send the /#default: ''/ message
then change MAMemento as per below so that if the memento cached value is
nil, rather return the default value for the description (which by default
is nil, MADescription class>>defaultDefault)
