"Look at elements at the time it's needed" is bad for interop, because 
looking at the elements of a plain array means, in general, calling 
arbitrary script.  Which means that to really get interop you need to 
specify exactly which elements are looked at when....

If we don't care about that level of interop, this is an option, of course.
