6108 * 2. Declare a typedef named my_cxt_t that is a structure that contains
6109 * all the data that needs to be interpreter-local.
6110 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
6111 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
6112 * (typically put in the BOOT: section).
6113 * 5. Use the members of the my_cxt_t structure everywhere as
6115 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
