Hmmm. Okay, thanks. What I really need to know is how many 
dimensions an array has and the total elements per dimension so 
that I can create temporary storage for it later.

      this(T)(T a)
      in(imported!"std.traits".isDynamic!T)
      {
          data = a; // data is of type Variant
          shape = [a.length, {?, ...}]; // what's the best way to 
deterine?
      }

Thanks,
