misunderstanding this entry in the CG.
I confess, I'm finding it difficult to apprehend this.
But the rehearsal mark will potentially be placed somewhere different
depending on the line breaking.
That was already the case when RehearsalMark.self-alignment-X
was fixed to CENTER (and the difference in system height was
more extreme).
If it's a problem now, was it a problem before? Is this change an
improvement? If there was/is a problem, can I prove it? Can I
find a case that triggers circular evaluation? Can I find a case
where a line break is poorly chosen due to the placement of
rehearsal marks? I don't know.
Can I play it safe by setting up a pure version of the callback that
returns a constant value like before? That would be pure, but I
don't understand whether it would be better.
Of course, this could all be wrong, but it's my best understanding of
how
pure/impure works.
Thanks for clarifying! :-D
