and it does not work for wrapping C++ code, right?

Just a small addition, to not have wrong impressions: There _are_ PyPy
extension modules. They are called mixed modules (since you can mix
app-level and interpreter-level code in them). It's just that they are
not really extension modules in the sense that you can compile them
independently from PyPy and load them as a .so (or whatever) later.
