not soon. i'm done with analysis and working on new code gen architecture. new lexer stuff is amazing.  my goal will be super small code for parser/lexers.  I'll have some results to show soon on lexer.  E.g., current v3 lexer generated from Java.g is 136k bytes of java code.  I'm hoping to get that down to a few k in bytecodes for an NFA VM that's close in speed to an optimized DFA.  The prototype NFA VM itself (needs more opcodes though) is only about 600 bytes of Java bytecodes. :)

I learned a lot about speed of NFA/DFA from Russ Cox, super genius:
