One additional point, to wrap the names of the elements of
recursive objects, I have used double brackets [[]] to
distinguish between a SEXP inside the SEXPR (this also used
for attributes) and single brackects for generic vectors.
For pairlist, I also use single brackets because it
is writtin in the Manual that they are converted in
generic vector of type pairlist when accessed from R.
The print.object function allows also to use the
"typefun" function (but this is a detail).
