??? Great, - now since extending of object by simply stating objname/new-word:
new-value is not working as it returns invalid path, how can we extend object,
once created? Can we do so only by creating new instance by cloning existing
object, and adding new word and its value during the time of creation? What's the
purpose of objects being so closed to further extensions? We now have 'protect
function available to protect some state and values, so why why to limit objects
in such way?
Aha, protect doesn't work on objects nor their values, being words, hmm ...
