[Push] Draft Push3 materials posted

[Lee Spector]

I've just posted some draft materials on Push3 to 
http://hampshire.edu/lspector/push.html. Scroll down to the Code 
section and see the "NEW DRAFT MATERIALS ON PUSH3" subsection.

Push3 includes a couple of significant new features (mostly suggested 
by and co-developed with Maarten Keijzer) that appear to make it much 
easier to evolve programs using complex, evolved control structures. A 
concise introduction to the new features is in the "Push3 vs. Push2" 
section of The Push 3.0 Programming  Language Description 
(http://hampshire.edu/lspector/push3-description.html).

What I've posted so far is the description document and the Lisp 
implementation. Maarten has developed a C++ implementation, for which 
he has also created a sourceforge project, and I've included the link 
to the sourceforge project on the Push page. HOWEVER, Maarten hasn't 
yet posted the code there quite yet -- it should be up in a couple of 
days, and I'll post another message here when it is.

Any and all comments would be very much appreciated!
