I've seen the fallout from trying to do that. It's a horribly bad idea ... > You get all the benefits of a C-like syntax without the overhead of > learning to deal with C and/or C++.

Java and OOP ? If you want to do things right, best to use something proper like Eiffel or Oberon. And Java will be most excellent at teaching about pointers (but there are no pointers!) to maximize the learning curve gradient ... On the upside your students will learn useless incantations along the lines of "publicstaticvoidmain!" that they can't explain and copypasta :) I've found these two a long time ago, and they still amuse me: http://gentooexperimental.org/~patrick/keywords.java.txt http://gentooexperimental.org/~patrick/helloworld.java.txt > In short, what's not to like for teaching?

I mean, apart from our insane idea to "build from source" which doesn't fit with the existing structures in the java ecosystem
