Welp, it's not much of a secret that the datatypes in REBOL
have these curious little corresponding numbers associated
with them.
The two missing types that you notice are not represented
directly in REBOL but are used internally. These types
don't have the full semantics of the rest of the "userland"
datatypes. (context! and symbol! respectively).
Pay no attention to the little datatypes behind the curtain!
