How do you tell pyximport to use the cython --cplus option?

Question

pyximport is super handy but I can't figure out how to get it to engage the C++ language options for Cython. From the command line you'd run cython --cplus foo.pyx. How do you achieve the equivalent with pyximport? Thanks!

One way to make Cython create C++ files is to use a pyxbld file. For example, create foo.pyxbld containing the following:

def make_ext(modname, pyxfilename):
    from distutils.extension import Extension
    return Extension(name=modname,
                     sources=[pyxfilename],
                     language='c++')
