title: SET-SOMETHING vs SOMETHING!
description:
SET-SOMETHING better looks in the manual page,
but in real code SOMETHING! looks better.

This is because ! and @ are special symbols easily distinguished by the eye,
while the word SET is not a special symbol, at least visually.

Since we care first of all about code, we must choose SOMETHING! .

In addition, a match for SET-SOMETHING is GET-SOMETHING, these two
words are different by only one letter. So the characters "ET-" carry
no information.
