While this @nogc code currently gives an error, the array could be allocated on the stack: ``` void main() @nogc { scope int[] a = new int[10]; scope int[] a = [1, 2, 3]; } ``` It's already done for `scope` classes and array literals passed to scope parameters. It has been brought up before (https://github.com/dlang/dmd/pull/11039#issuecomment-613518685) but I don't see a bugzilla issue for it yet.
