  If this is a struct, then there is no "special compiler handling" needed to cast a struct to a pointer using opCast() (except for static arrays).

  But, from programmer point of view, array is not a struct, just a type with some properties, "struct" is hidden somewhere internally.

  I see no danger in using cast(void *)Array instead of Array.ptr, if semantic is known in advance (and it is).

  IMHO, it would be not so good if this handling will be disallowed at some point.
