One thing that I find bad about it is that we lose a straightforward
relation between input and output.  Our durations are composed of log2,
dots, and scale factor.

We then get a mushy "duration is the following rational, can I have
tuplet brackets with that somehow?" instead.  Why is there no notation
for \times 2/3 c1 ?

Well, "music argument after left-out optional argument" at the current
point of time means "closed music".  It is likely a safe bet that we
rarely need a single note for a tuplet, so it is not much of a problem,
and I am chugging away at getting the "closed music" thing scrapped, but
that's still a month left at least.

What possibly would make sense as an optional argument would be a
setting for tupletSpannerDuration.  I am not sure about it, though,
since one would usually want the same duration for a number of calls.

While we still have the [talk] tag, we could use the name \tup-let for a
version automatically using baseMoment for tupletSpannerDuration, and
\tuplet for no subdivision.
