that's the obvious solution, of course.  cf. existing shortcuts:

$ grep -n INLINE Python-2.4.1/Python/ceval.c
1103:                           /* INLINE: int + int */
1133:                           /* INLINE: int - int */
1156:                           /* INLINE: list[int] */
1305:                           /* INLINE: int + int */
1335:                           /* INLINE: int - int */
1967:                           /* INLINE: cmp(int, int) */
