I think this is a misunderstanding. Drew meant the answer on "how to
call a function" was to be found in the elisp intro. The yes-or-no-p
thing was just an additional note.
Incidentally, if anything, testing for t is more correct. :) The doc for
`y-or-n-p' clearly states, it will return t for "yes". It could be
extended to return 'cancel without changing the interface. Using any
non-nil value as "yes" is indeed an assumption. (Not that it's likely
to break, or that I haven't made that assumption myself...)
