A few details:
- Pallene is a friendly fork of Titan [1]. The reason for the fork is that the authors of Titan are iterating fast and adding many experimental features to it. The research group at PUC Rio needed a more stable code base and language definition. Improvements from Pallene will be merged back into Titan, which is probably what actual programmers should use in the long run (as of now neither is ready for production).
- There was a presentation of Pallene at Lua Workshop earlier this month. Slides and video should be available at [2] at some point.
