That means (+ . (1 2 3)) does what you want, doesn't it?

Granted, to do the equivalent of (+ @(foo)) you would have to do;

  (let temp (foo)
       (+ . temp))

Which is not very nice at all, so I'm not arguing against @. On the contrary.

Edit: I used to think that . and @ would only differ in the sense that cons and splice have different list building semantics, but now I believe that they should also differ in the timing of the operation;

  (+ . (foo))  -> (+ foo)
  (+ . '(foo)) -> (+ quote foo)
  (+ @(foo))   -> what we want, given that foo returns a list
  (+ @'(foo))  -> (+ 'foo)
