No. Casting other structs (*not* pointer to struct) is in fact illegal.
(This just occured to me, I didn't think of this when writing the other
post)
If you want the address of the struct you write void *foo = cast(void*)&s;
So the only sane thing to do is either to forbid casting an array to a
pointer or to return .ptr like it's done now.
I don't see the harm in the latter, but then again arr.ptr is shorter
and more readable.

So my only remaining objection is: Allowing it doesn't hurt (IMHO) and
disallowing may break existing code, so why bother ;)
