Slightly less dirty would be something like this:

\version "2.11.28" % should work on versions all the way back to 2.8

looksFaster = #(define-music-function (parser location music)
                                    (ly:music?)
            (let ((new-music (ly:music-deep-copy music)))
             (shift-duration-log new-music 1 0)
             new-music))

\score { \looksFaster { a4. b4 c b8 a g a4 b8 a }}

...but there could be an even simpler way.  Have you checked the manual?
