Try this code snippet in emacs-lisp-mode and you should see the function
name after @ not font-locked:
(defun who-@-how ()
)

That's because of its "prefix" syntax for use in ,@.
I guess we could change its syntax from "'" to "_ p".
Can someone try it out and install that change if it seems to work well?

Seems to work well. Since this is a regression, I suppose it should be
in emacs-24? If so I'll take care of this tomorrow.

Not sure why you think it's a regression, but yes you can install it in
emacs-24.

I mean the code snippet is font-locked correctly in 24.3.
BTW, in emacs-lisp-mode-syntax-table why are all entries end with some
whitespaces i.e. instead of
(modify-syntax-entry ?@ "'" table)
it uses:
(modify-syntax-entry ?@ "' " table)

Aha, didn't realize that. Not sure why that changed.

It makes no difference, but this style was very common. It's probably
because syntax strings are "positional" (the first char has a meaning,
the second another one, the rest yet another) so using "' " is saying
explicitly "no p/b/1/2/3/4".
