As already said in private, I like that name. Very descriptive :-)

As already said on the list, I like Mozart/Oz but not its syntax. Here
are two links that I hope useful:

1. oz kernel language
http://www.mozart-oz.org/documentation/tutorial/node1.html#label2

It says that other language constructs are built on top of that.

2. hierarchy of primary types
http://www.mozart-oz.org/documentation/tutorial/node3.html#label14

What about reusing the idea of record that serves as a basis for a lot
of higher-level constructs (dictionnaries, tuples, classes and objects, etc.)
See also http://www.mozart-oz.org/documentation/tutorial/node3.html#label19

IMHO, the goal we are trying to achieve can not be a new idea. Looking around
for research papers and research languages is a good way not to completely
reinvent the wheel.

HTH.
