Are you sure that you understand how the compound-time Scheme function

No me either :-). Actually, I use:

barlines = { \repeat unfold 8 {s16*7 \bar ":" s16*7 \bar ":" s16*11
| } }
\score {
\new Staff <<
\barlines
\relative {
\tempo 4 = 126
\key e \minor
\time 25/16
\set beatGrouping = #'(3 4 3 4 4 3 4)
#(override-auto-beam-setting '(end * * 25 16) 3 16)
#(override-auto-beam-setting '(end * * 25 16) 7 16)
#(override-auto-beam-setting '(end * * 25 16) 10 16)
#(override-auto-beam-setting '(end * * 25 16) 14 16)
#(override-auto-beam-setting '(end * * 25 16) 18 16)
#(override-auto-beam-setting '(end * * 25 16) 21 16)
...
}
}

The one could refine, so that the 4's have a common beam, but the
second beam is broken in groups 2+2. In the scores of the region,
sometimes that is done, to show a metric subaccent pattern. So the
above beatGrouping might be changed to:
\set beatGrouping = #'(3 2 2 3 2 2 2 2 3 2 2)
But the right/left stemming might come out wrongly.
(I am working a bit on this beaming problem, and I come as far as
writing a Haskell program that can write LilyPond code.)
