I do not understand well. Bind take a word and change it to another word bound
to an existing context, but only if that word already exist in the context. It
can't add a new word to a context. This can be done only for the global
context by Load and by make (any)word! There are 2 distint actions: 1) adding
a word to a context, 2) bind a word to a context.

You are right, it is only question of evaluation order.
So we can be sure that an object is an exact reproduction of internal rebol
context. :-)
But i always want a get-context for use and function context. :-(
