Find objects within a spanner

[Urs Liska]

Hi all,

if I override a Tie/Slur's stencil I can easily (well, now, after your
help ...) get to the note columns at both ends.

Is it possible to retrieve a list of all objects *between* those ends too?
Concretely I would like to know if there are ties within a slurred
phrase and to determine peak notes/stems in order to do some sort of
collision-handling-like layout decisions.

TIA
Urs
