wpython has reached 1.1 final version. If you are interested, you can find it here: http://code.google.com/p/wpython2/ and you can download the new slides that cover the improvements over 1.0 alpha.

I change the instruction format from bytecode to wordcode, too (because it allows for more efficient instruction decoding).

Did you used wpython wordcode format, or a new one?

Contrary to his approach, however, I do not change the instruction encoding to pack in additional optimizations. (I hope to have put that correctly; I have seen his slides about a year ago.)

Yes, you're right. wpython approach is to encode as much information as it can to save space, decoding time, "specialize" some opcodes, etc..
