I  already told in the first post that I've implemented __str__ function, but it doesn't
seems to be automatically called.
For instance, the following example won't work:

>>> class a:
        def __init__(self, i):
                self.i = i
        def __str__(self):
                return "magic_function_{}".format(self.i)
>>> t = a(0)
>>> str(t)
'magic_function_0'
>>> "".join([t])
Traceback (most recent call last):
  File "<pyshell#13>", line 1, in <module>
    "".join([t])
TypeError: sequence item 0: expected str instance, a found
