Each answer seem to bring up new questions again ;)
What exactly do you mean by "loading" words without using 'load ?
Do you mean that (for example) something like "test: 5" defines a word named
test of type integer? and with value the number five and that this word is not
stored in the system/ words but in an internal non accessible list of words ?

I guess that by "partially" you mean "only for the context that your script(s)
have knowledge of" ?
Would that mean that, for example, one would have to store all code and data
within a single object to make sure everything he needs is correctly restored
(puting aside the need to handle circular references properly) ?

How could I not see it ???
I lack vitamins for sure ;)
