[Python-Dev] [PEP] += on return of function call result (original) (raw)

It seems almost within the bounds of possibility that pychecker could learn to find bugs of the form t = expression # t results from computation t += i # inplace op on (immutable/no-iadd) t del t # or t otherwise not used before function return by doing type and liveness analysis on t. (the type analysis being the hard part)

Is there any time that the described situation would not be a bug? I can't see it.
