I think it could work like this:

    SUITE_LIST(suites) {
        suite1,
        suite2,
        // ...
    };

    GREATEST_MAIN(suites);

but, again, I don't know if that's necessarily an improvement. RUN_SUITE is encapsulating saving the suite's name, optionally only running suites with names that match a certain pattern, and some other features that become tricky to implement with just a statically allocated function pointer array. I'm also trying to avoid doing anything "clever" with macros.
