Well, this is clearly a hack. I’m surprised that Lily doesn’t complain. 
More precisely: it’s improper to use two voices and fake the look of one 
voice by tweaking stem direction. And it won’t work in any but the 
simplest cases. Also: please, for the sake of legibility, please put 
spaces around _every_ { and = and \\. The \\ should get a line of its 
own, unless the entire <<>> expression is placed on one line. It’s just 
imprudent to be so greedy with space at the expense of legibility, and 
if you’re publishing your code, it’s not a matter of your personal 
preference alone.
