4018 * 1. #define MY_CXT_KEY to a unique string, e.g.

4021 * all the data that needs to be interpreter-local.
4022 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
4023 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
4024 * (typically put in the BOOT: section).
4025 * 5. Use the members of the my_cxt_t structure everywhere as
4027 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
