Is there a fundamental reason why structs can have constructors but not destructors? I knows structs are stack based, but a destructor may still be necessary if we manually allocate memory in them.

For example when I try to compile the following test

struct Test
{
    int* pointer;

    Test()
    {
        pointer = new int[10];   
    }

    ~Test()
    {
        stdout.printf("Destroying!\n");
        delete pointer;
    }
}

void main()
{
    var p = Test();
}

I get an error message:

error: unexpected declaration in struct
    ~Test()
    ^^^^^^^
