Thanks for the explanation.
Apparently I misread the documentation.
[detailed explanation snipped]
I had a memory that the syntax had changed but couldn't find it upon a
quick look since all the examples at the beginning of the notation
reference still use the old syntax :)
You can likely write
\repeat unfold 8 { ... } \alternative { } ...
in order to quench the \repeat unfold's thirst for an alternative.
While it looks a bit ugly or overdone it probably is what I will start
to use (as it removes disambiguities from my code)
It would probably be better if the default resolution was in direction
of the new syntax, but I don't think that this is trivial.
Thanks David and Valentin for the extended explanation.
Kind regards,
Michael
