We proudly present the first internal prototype release of the Stockhausen system. We call it "Operette 1".

Stockhausen implements the language Alice, which integrates features from Oz/Mozart with the language Standard ML. Moreover, Alice includes other interesting features found in neither of both languages. Besides implementing almost complete SML, Stockhausen Operette 1 already supports:

• higher-order modules: a more powerful module language
• components: type-safe dynamic loading of modules
• laziness: combining strict and lazy functional programming
• futures: "logic variables" and concurrency

Important design goals for Alice/Stockhausen were backward compatibility with Standard ML, as well as interoperability with Mozart. Stockhausen Operette 1 is based on the Mozart virtual machine. Operette 1 programs can therefore interoperate with Oz.

The following people are currently involved in the Alice/Stockhausen project:

• Thorsten Brunklaus
• Leif Kornstaedt
• Andreas Rossberg
• Gert Smolka

Printed out on paper it will certainly prove to be a very useful item that is happy to stick to any wall available!
