peer-reviewed and portable C++ source libraries. The libraries are intended to be widely useful, leveraging and extending both the C++ Standard Library and the Boost Libraries.
an experimental Python-to-C++ compiler. It accepts pure but implicitly statically typed Python programs and generates optimized C++ code. (Google sponsoring)
it is possible to execute Python code at speeds approaching that of fully compiled languages, by "specialization". The current prototype operates on i386-compatible processors and shows 2 to 100 times speed-ups, depending on code.
