The answer is no. This is an ongoing discussion on this mailing-list: stay
tuned.

Basically, contrary to "float", "symbol", "pointer", the "list" type is
not an atom-type, it's only a message-type. I am proposing the addition of
a list atom-type, although it needs a different name and won't be
compatible with other lists.

In the meanwhile, GridFlow and some other libraries are faking nested
lists in PureData, but it's slow and ugly.
