    I suspect that the best option is probably to make that thing a unnamed
    union of the actual different types the different restart cases needs,
    which also allows you to name things appropriately and not have any wasted

    Leave the arg0-3 ones around as one of the unions, both to avoid having to
    change other things and to have a "generic" one for stuff that simply
    doesn't much care (in order to not have tons and tons of substructures to
    the union when most users really don't need any fancy types).

    I think we already depend on recent-enough gcc's that unnamed unions are
    ok and we don't need to play games with naming.
