      pystr;
    ==> 'python string '
      pyobject pyint = 2;
      pyint;
    ==> 2
      pyobject pylst = list(pystr, pyint);
      pylst;
    ==> ['python string ', 2]
      pyint + pyint;
    ==> 4
      pyint * pyint;
    ==> 4
      pystr + pystr;
    ==> 'python string python string '
      pystr * pyint;
    ==> 'python string python string '
      python_eval("17 + 4");
    ==> 21
      typeof(_);
    ==> pyobject
