The implementation of D. was buggy. I hope we can do better with the
addon. I thought there was a rudimantary D.-replacement in the addon
but my memory may be faulty.
With enough Jers contributing maybe this could be a competitor to
Mathematica. Time will tell.

Yes, rank 0 a valid assumption. Sort of:
J used to have two derivative words, d. (rank 0) and D. (jacobian).
As near as I can tell, the library only replaces d. and does not yet
provide a D. implementation.
That said... I would not think of this as a mathematica competitor --
more like an early version of macsyma.
