I missed these warnings in C modules.
*array*
"fromstring" and "tostring" methods
*io* (like _pyio)
argument "max_buffer_size" of BufferedWriter and BufferedRWPair
*sys*
"sys.getcheckinterval" and "sys.setcheckinterval"
and some complaints from Objects/typeobject.c:
"object.__init__() takes no parameters"
"object.__new__() takes no parameters"
"object.__format__ with a non-empty format string is deprecated"
"Type %.100s defines tp_reserved (formerly tp_compare) but not "
"tp_richcompare. Comparisons may not behave as intended."
