No you're not.

Array was designed before the @nogc attribute was created, so it wasn't
coded with it's requirements in mind. Looking at the code, Array
allocates GC memory for exception throwing in some cases. These can and
should be changed to asserts.

I am writing a PR now to fix this. There doesn't seem to be too many
cases to fix.

Is there a way to use Array in @nogc code:
```
import std.container.array : Array;

@nogc:
void main(string[ ] args)
{
   Array!int ai;
   ai ~= 1;
   assert(ai[0] == 1);
}
```
fails:
```
main.d(8): Error: @nogc function 'D main' cannot call non-@nogc

main.d(9): Error: @nogc function 'D main' cannot call non-@nogc

am I doing something wrong?
