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:
