When in doubt, you can always make do with the following:

triplet = #(define-music-function (parser location tuplet-span music)
 ((ly:duration?) ly:music?)
   (if tuplet-span
        #{
                \tuplet 3/2 $tuplet-span $music
        #}
        #{
                \tuplet 3/2 4 $music
        #}))

Just using the default #f for a defaulted value can save a lot of
thinking sometimes.
