Oh.  One element per note is tricky.  How about making this a music
function instead that outputs lyrics?

diffints =
#(define-music-function (mus) (ly:music?)
  #{ \lyricmode { $@(map ...) } #})

That's what I can suggest for now.  But that request seems legitimate
enough that I'll see what it takes to make lyricmode accept a markup
list.  You'd use it presumably as

\markuplist [optional duration]

But I have no idea what to do with things like hyphens at the end.
Probably attach them to the last element.  And the duration would likely
be for all of the syllables?  Or just the last?  Not that it would be
important since one would usually just use this in \lyricsto stuff where
the syllable length gets overridden.
