You are invited to join the Compiler SIG: http://www.python.org/sigs/compiler-sig/
The Web pages about the SIG still need a lot of work, but they provide some indication of the SIG's purpose:
This SIG provides a forum for discussing compilation and program analysis issues. Unlike most SIGs, it does not have a specific mandate or deliverable. There are several independent projects to develop compilers, type checkers, and related tools.
Ka-Ping Yee took notes on the Dev Day session on compilers. It provides more background about the SIG:
I am putting together a list of Python compiler and program analysis projects. If you are responsible for such a project, I'd appreciate it if you could send me a URL and a brief description. I'll post the final list on the compiler-sig Web page.
