Comment #13 on issue 2858 by address@hidden: Document \shape music function
http://code.google.com/p/lilypond/issues/detail?id=2858

Adding to comment #8: the problem with the tweak form having the music  
first is that it works reasonably well only when \shape is the only  
function that does things like that.  As soon as multiple commands are  
being used with that convention together, they have to be nested in  
unsavory ways.

The \no and \hide commands don't have that problem since they have only a  
_single_ argument.  Now of course we can give the \shape command a
string-or-list? argument first, and a list-or-music? command afterwards,  
and check and complain about the combinations list-list and string-music in  
the function itself rather than letting the signatures sort this out.

But this seems quite awkward.  So I think,  
for "tweak-or-override-with-parameters", we should likely bite the bullet  
and place the grob property path last consistently.
