Native Collection Initializers

It would be a nice convenience feature is some native collections could be defined with collection initializers:

Code (CSharp):

1. NativeArray<int> intArray = new NativeArray<int>(3, Allocator.TempJob)
2. {
3.     5,
4.     10,
5.     1
6. };
7.  
8. NativeList<int> intList = new NativeList<int>(3, Allocator.TempJob)
9. {
10.     5,
11.     10,
12.     1
13. };

^ That code will fail. But it would be nice if it didn't.

I assume there's a good reason unity hasn't supported collection initializers for their native collections. Does anyone know why it might be?

Thanks for any input.
