Hi, all, I'm a newbie in python and python implementation. I just read this thread. It's no better to me to devote some effort on the JVM backend in pypy. That could be a little hard for me but cool. And I need to write my master's doc the next year too! It's a good opportunity for me to study on the details of a language implementation.
Shall we just do something or help each other?
