    This is a different form for this first warning-2 declaration
    than the first warning-1 declaration.

    Maybe this should be := instead?

    Maybe there's a way to do something akin to

    warning_type(level, option)

    So these become

    warning_type(1, extra)
    warning_type(2, aggregate-return)
