This should work since 0.39, but as always with data structures: This
is an area that's changing a lot with every new Miller-Pd so I'd
recommend to use 0.40 instead. With that, you can [set] and [get]
symbol fields as shown in attached patch. Setting them on creation
with [append] doesn't seem to work yet, however, at least I couldn't
make it work.

Ciao
