Hi Paolo,
> https://en.wikipedia.org/wiki/Coupling_(computer_programming)#:~:text=In%20software%20engineering%2C%20coupling%20is,of%20the%20relationships%20between%20modules
"In software engineering, coupling is the degree of interdependence between software modules; a measure of how closely connected two routines or modules are;[1] the strength of the relationships between modules."
So you're trying to apply the definition of "routines and modules" to describe data and how it's referenced in a layout application? ;)
No. I'm applying it in its *natural* context (the programming code of LP, that couples two functions, and this appears to me as an issue. I could be wrong, but it deserves to be discussed, IMHO, and this is not offending anyone)
I can't spend any more time on this thread — I hope you figure out your solution soon, and stop blaming Lilypond for something it's not actually doing.
I'm not blaming *anything*/*anyone*. Please, go on in saying nonsense things: I'll just ignore you!
Cheers
P
