That's certainly more compact, but I've not used it because I'm more
interested in avoiding long "instrumentalist" beams in favour of
shorter ones, even with half-note beats, because I set vocal music.

(In the attachment, \score makes a \layout local, so that exx. 1 and 3
don't see them. Compound time is unaffected, because the \layout time
signatures never have 8 in the denominator, so no match.)

Cheers,
David.
