of course I read the error-message, I understand the error-message, BUT
this message is not telling me how anyway to save the data of such a
class in a file! It does not tell me, that there is absolutely no way
to do that. Maybe there is, maybe there is not.
Thats why I am posting it here!
"A man who wears a hat without buying a ticket cannot enter the theatre"
You wear a hat, you want to enter: either buy your ticket or forget
about your hat.
In this case, just define a __getstate__ method (read the pickle
docs), or forget about __slots__.
