should be dead" warning for saved init data

Ok, got it.

SCM
make_music_function (SCM signature, SCM func)
{
  scm_set_object_property_x (func, ly_symbol2scm  
("music-function-signature"),
                             signature);
[...]

The signature is implemented via object properties, and those are  
implemented via weak hash tables outside of the object itself.  Not  
normally a problem, but if we have default values there that are a music  
expression, those will be considered to be of a type that should not make  
it across sessions, and not inside of an "undead" object where its survival  
would be permitted.

Have to think about that one.
