I believe that self is always passed, whether you have an instance of
the uno class or not. Since you did not tell m() to expect self to be
passed to it, and self is passed anyway, m() has this self and has no
idea what to do with it. Also, you must make an uno object (u=uno())
then call methods off that object (u.m()) since not doing so means the
uno class will not get initialized.
