One can, of course, exchange the order of arguments. However, then
adding several arguments becomes more awkward:
at =
#(define-music-function (parser location music event time)
(ly:music? ly:music? ly:duration?)
"Place @var{event} at a relative duration @var{time} in relation
to @var{music}."
#{ \context Voice << { \skip $time <>$event } $music >> #})
{
\at {
\at { c'1\p } \< 4
} \! 1*2/3
}
In this case, we might get the same result, however, by specifying the
second duration not in relation to the "main" event but to the already
delayed event:
after =
#(define-music-function (parser location music time event)
(ly:music? ly:duration? ly:music?)
"Place @var{event} at a relative duration @var{time} in relation
to @var{music}."
#{ \context Voice << { \skip $time <>$event } <>$music >> #})
{
\after { c'1\p } 4 \after \< 1*1/6 \!
}
This is now in "time order" but I am not really convinced that it is
less confusing.
