I got wondering if REBOL's case-insensitivity could be put to good use
with this problem, and came up with the following. Not much
difference in code-size to your approach, but different-looking,
anyway...
rebol []
text: input
forall text [
letter: to-string text/1
if all [letter >= "a" letter <= "z"][
text/1: text/1 + either letter < "n" [13][-13]
]
]
text: head text
print text
