This is not

because this is the type of a function pointer

Do not call `__delete` here, use `destroy`. `__delete`

If you are sure the element can be destroyed, you can call destroy():

enum someSpecialInitValue = 777;
struct S
{
int i = someSpecialInitValue;
this(int i)

dmd only makes that an error if you specify `@safe` and i think
