@safety of Array

[Brad Roberts via Digitalmars-d]

I've been spot checking parts of phobos today to see what all isn't 
@safe ready.  I'm not shocked that Array isn't, but doesn't it need to be?

For instance, not even the most basic of uses works:
$ git diff -U5
diff --git a/std/container/array.d b/std/container/array.d
index 4a1bfb4..2672bc6 100644
--- a/std/container/array.d
+++ b/std/container/array.d
@@ -826,11 +826,11 @@ $(D r)
         length = offset1 + tailLength;
         return this[length - tailLength .. length];
     }
 }

-unittest
+@safe unittest
 {
     Array!int a;
     assert(a.empty);
 }

==> std/container/array.d(833): Error: safe function 
'std.container.array.__unittestL831_1' cannot call system function 
'std.container.array.Array!int.Array.~this'

I know it's a tricky implementation, but let's focus on the goal.. 
should Array be usable in @safe code?
