How about we change \repeat ... \alternative in its structure to be
\repeat ... { \alternative ... }, namely introduce a separate music
expression for \alternative? That way neither \repeat nor \alternative
need to be special.
Either \alternative could send some events caught by \repeat (with
\alternative being right behind \repeat being the last opportunity to
catch them, with \repeat \repeat ... \alternative possibly being tricky)
or a scorification hook does the final assembly.
Then we'd not need a special syntax (and the lookahead needed by
\alternative is a real nuisance) and could relitigate the meaning of
\repeat 4 .
