I would have expected the original assignment to fail, but the parser
at that point seems fine with the comma as an alternative to a period
for defining a symbol list. However, then, at the point of
referencing the variable, the parser is not able to form a symbol list
in the same manner.
I’d be fine with that. There are two ways that symbol (or key?) lists
are used: in a hierarchically vertical or horizontal way.
Referencing an alist value as in
\foo.bar
definitely falls into the ‘vertical’ category, while
\tagGroup score,part,vocal-score
is definitely in the ‘horizontal’ category.
The comma-separated syntax is only intended for ‘horizontal’ uses, IIUC.
