1) Context means ... CON = "with" text = "body of word"
2) REBOL MAKES context from a Prototype ("OBJECT") definitional.
UNTIL REBOL MAKES context, the script of REBOL is just symbols
without meaning.

A REBOL prototype ("object") is a structure that supports these:
1. defining aspects
2. naming defined aspects
3. accessing named aspects using path notation
In other words, a REBOL prototype ("object") is just a fancy
block with a fancy way to "name the elements" inside that block
and access those elements inside that block using named path
notation

Ordinary blocks only allow for IMPLICIT naming of elements
contained therein, which requires one to
1) remember their sequence
2) use any of these for retrieval:
ordinal phrases (first, second, third ... [ ])
pick phrases (pick [ ] n) *
select phrases (select [ ] 'selector-word)
path phrases ([ ] /n) *
extract phrases (extract [ ] n) and (extract/index [ ] n m) *
* where n = any integer; m = any integer
