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
