LOAD/markup also does not create words. TAGS and STRINGs are
not words. :-)
Brings up an interesting question. If you are writing a
script which inspects a lot of other scripts, what you can
do is use LOAD/next/header instead of just LOAD.
LOAD/next/header %script.r will return a block with the
header object in the first spot and the rest of the script
as a string in the second position. This means only the
words in the header are added to system/words and most of
the time REBOL script headers have the same words so nothing
more is added. You can load/next/header tons of REBOL
scripts and inspect them with reasonable confidence that
words will not grow scarce. (In fact, since all of the
standard words of a header are already in the system object,
you won't likely add any words at all:
foreach word next first system/standard/script [
print [word found? find first system/words word]
]
(This is the present and future behavior of
LOAD/next/header, at least. Early versions, possibly 2.3,
may have returned something slightly different).
