I then stumbled over this paper:

International Journal of Mathematical Education in Science and
Technology, 1464-5211, Volume 17, Issue 2, 1986, Pages 239 – 245

Not having LIST and DICT as part of the base language would make sense
if user contributions were encouraged.  After all that would make way
for evolving the base/primitive language by selecting the most
successful contributions.  IMHO this is where python modules have been
a big success story as it helps time proof the language by allowing
the language to embrace new technologies as they establish themselves
in the market place.
