5553 * 2. Declare a typedef named my_cxt_t that is a structure that contains
5554 * all the data that needs to be interpreter-local.
5555 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
5556 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
5557 * (typically put in the BOOT: section).
