Thanks for looking! However, I had second thoughts about this
formulation. Mainly, the fact that one of the output arguments is part
of the macro is kinda icky. So I decided that a simpler, less
innovative option is to just use a bits32 argument to carry the input
booleans, and let the output boolean be a separate argument (which I
also moved to appear last in the argument list, as we normally do).
This also means the list of indexes continues to be its own argument.
But, as I said, this is less innovative, which I think is mostly good.
And it definitely reads better than currently.

There might be places in executor.h to reuse the f831d4accda0 thingy,
but this is probably not it.

Thanks,
