This will be v3.4 I think. I've had to put v4 off into nebulous future. My priorities flipped recently. I'm going down this path:
1. finish STv4 and doc; release
2. completely revise/gut antlr ref guide book
3. simultaneously, go nuts on bug fixing and a few big features for antlr
Background threads:
* design new prog. language to take over world.
* collect notes for future coding book
