Took me a while to realize that << \partial { s4 } { ... } >> would 
work. Also, what about injecting \partial into music via \pushToTag, the 
edition engraver or similar?

Generally speaking, \partial is so frequently used that I am decidedly 
wary of breaking it. Like Lukas, I am not seeing clearly on the English 
terminology of "partial", "anacrusis", "upbeat" and "pickup", but it 
seems to me that the choice is broad enough to allow the introduction of 
a separate command. I don't know if I like it. It will be more to learn 
for the same thing, but it might be more convenient for cases where you 
need \partial 1*5/16 and such.
