reading properties

[Rune Zedeler]

I consider it very hard to read properties from within lily.
The problem is that you need to pass a pointer to some sort of musical
expression - and I don't know how to get such a pointer.
I.e. when thinking about the ottava-implementation it would be nice to
replace

  \property Staff.centralCPosition = #-13

with

  \property Staff.centralCPosition = #(- (ly-get-context-property
"Staff" "centralCPosition") 7)

But the "get-translator-property"-function needs to get a pointer to the
Staff rather than just the "Staff"-string - and hence the above does not
work...
Is this something like this currently possible at all? Othervise this
would be something nice to allow before 1.6, imho.
