Hi Paolo,
it seems like you have some very specific setup of lilypond files and
framework and need a solution that works within that, but you’re trying
to avoid explaining the whole setup either because it’s too much effort
or for privacy or similar. From my experience, when I get into that kind
of situation I have usually ended up in some kind of ‘rabbit hole’ and
the problem would be easier solved with a different setup in the first
place.
Can you describe the reason why you need this?
Best, Simon

I need to override a property of StaffSymbol, for every staff, outside
any music expression/block context. Probably I'm not using the right
words even now.
But what I need is a sort of a "global" variable which is set for any
staff without having to put it into some music expression (like
\layout {\context {...}} , or \new Staff \with { ... } etc.).
This is why I asked if is there a Scheme solution
