Hi David,

Well at least now you’ve asked the question you clearly meant to ask earlier,
in a way that someone other than you can figure out how to answer in the way
you’re expecting. =)

That seems fine to me.

Correction: Lilypond doesn’t, by default, give a “unique printed
representation” to (ly:make-duration 4 0 4/5) as compared with
(ly:make-duration 4). On the other hand, I am fully capable of making Lilypond
do so, i.e., formatting the denominator as a sixteenth note *with a '5'
[possibly in a bracket] below it*, which absolutely *is* a “unique printed
representation”, and will convey to the performer exactly the desired meaning.

I can do the math to back-calc either of those into a note duration in order to
determine. So I guess here’s my [final] answer to your question: I’d like to
see (cons 8 20) replaced with whatever is easiest for the lexer / parser to
convert to and from and/or pass through to the time function(s) without losing
any critical information about the denominator duration.
Feel free to ask me for yet another answer to this question… but be warned that
I don’t know enough about the lexer or parser or Lilypond’s internal
representation of durations to give a more specific or nuanced or helpful
answer than that. ;)
Cheers,
Kieren.
