I think this has been tinkered about with at some stage, so it doesn't
quite behave the way the FAQ now claims:  I have to repost the FAQ (a bit
late) so I'll alter it.  The short answer is that in recent versions
of the shell you need to set the option kshautoload.  Otherwise,
the file is treated as containing a definition of the function
(rather than the body of the function) if and only if the file's
executable contents are just that definition and nothing else.  This
is to try and guess the user's intentions.  With kshautoload set it
does what you're expecting, no guessing.
