+> How about the following counterproposal. This also changes some of
+> the other format codes to be a little more regular.
+>
+> Code C type Range check
+>
+> b unsigned char 0..UCHAR_MAX
+> h signed short SHRT_MIN..SHRT_MAX
+> B unsigned char none **
+> H unsigned short none **
+> k * unsigned long none
+> I * unsigned int 0..UINT_MAX
+
+
+> i int INT_MIN..INT_MAX
+> l long LONG_MIN..LONG_MAX
+
+> K * unsigned long long none
+> L long long LLONG_MIN..LLONG_MAX
+
+> Notes:
+>
+> * New format codes.
+>
+> ** Changed from previous "range-and-a-half" to "none"; the
+> range-and-a-half checking wasn't particularly useful.
+
+Plus a C API or two, e.g. PyInt_AsLongMask() ->
+unsigned long and PyInt_AsLongLongMask() -> unsigned
+long long (if that exists).
