Looking to learn something new?
What means "in a sane state"?
(I'm italian and just for curiosity I would know the meaning that it has in programming context) I head it at 3.25 in the chapter "Syntax Overview"...

In this case it means that a valid object is returned. The method
alloc allocates memory for the object but does not initialize it. The method
init initializes it to a valid state and sometimes even with some default values.
