AFAICT REBOL doesn't distinguish between "code" and "data". The
loading process simply turns a string (what you typed into the
console window or read from a disk file) into an internal structure
(i.e., block) that can *either* be evaluated for effect/value or
be navigated as the subject of other evaluations. It *is* my belief
that the string typed into the console window has a limited lifetime,
and it is possible for loading to create blocks which nothing refers
to after a short while...

Perfectly OK to play with it at home, just don't expect to make a
living writing such things... ;-)
(You can supply your own puns regarding the contrasts between:
private public
local global
at home in public
;-)
