Yes. As I've added some commits recently I'll link the line of code so
that the reference will be safe:

I would also add:
array=(
x y z
)

I hope that I've could help. I think that what's practically useful is
the TOKEN_TYPES array that's taken from z-sy-h/f-sy-h and extended,
and its way of use to decide on the state change that the parser
should undergo.
