Dear all,

The virtual machine of the Mozart system is in dire need of a refresh! It was originally designed in the early 1990s (twenty years ago!) and is now showing its age. We are working on a new virtual machine that is ready for the future. But some of the issues are still not clear, in particular how to represent the data. Yves Jaradin has prepared a detailed discussion of the issues.

We would like to ask advice from the experts on LtU. What is the best way to write a virtual machine today? Is it possible to be simple and still efficient? Please let us know what you think.
