Of course, there is considerable groundwork to make this a reasonably
simple addition of a music function, and there were a lot of discussions
on the mailing list.  The principal shortcoming that this feature was
supposed to address is the ability to specify more than 2 voices in
top-down manner, and that basically now means

\voices 1,3,4,2 << \soprano \\ \alto \\ \tenor \\ \bass >>

which is ugly enough as it is but better than the previous

<< \soprano \\ \bass \\ \alto \\ \tenor >>

particularly because the latter makes even more of a mess of \relative
mode than you already have.  And we couldn't agree on changing the
numbering used for << ...\\...\\... ...>>, so making it easy to override
it seemed like the next best thing.

I like the results well enough that I advertise their use where I feel
they make sense.
