I probably prefer 2. It uses lily definitions instead of Scheme definitions.

If you're going to use 1, you'll need to put a # in front of each line.

I don't like set 3 -- it's all compressed together and is hard to read.  But
as long as the resulting scheme variables are exact, then it's OK, too.

Actually, I'm not sure that being exact matters, since a hundredth of a
point is much lower than the resolution of my printer.  I think we've had
that discussion before.  And it doesn't hurt to go to the exact, in my
opinion.

Thanks,
