[Python-Dev] Type of range object members

[Alexander Belopolsky]

The range object is currently defined in Objects/rangeobject.c as

typedef struct {
	PyObject_HEAD
	long	start;
	long	step;
	long	len;
} rangeobject;

Is this consistent with PEP 353, or should Py_ssize_t be used instead of long?

It looks like some of the code in rangeobject.c is already Py_ssize_t
aware (see range_item and range_length), but it assumes that it is
safe to cast long to ssize_t and back.
