You don't have to; static member functions can always be invoked from
Python as:

    Tag.str2()

mirroring the C++

    Tag::str2()

The fact that you can write

    tag_instance.str2()

in C++ is almost a quirky accident. If you want to be able to write that
from Python, your best bet is to write a "thin wrapper function", and pass
that to def():

std::string my_str2(Tag*) { return Tag::str2(); }

...

        .def("str2", &my_str2)


Eventually, we will have a way to define Python static functions so that
you can write both

    Tag.str2()
  and
    tag_instance.str2()

from Python.

HTH,
