Currently if you want to allow a @property function to be called with both a
single element type or an array of such elements types, you need to provide two
property functions, for example:

-----
struct S
{
    @property void selection(int[] arr) { }
    @property void selection(int arr) { }
}

void main()
{
    S s;
    s.selection = 1;  // select one item
    s.selection = [1, 3];  // select multiple items
}
-----

But it would be simpler if we allowed a variadic parameter in a property
function:

-----
struct S
{
    // one property
    @property void selection(int[] arr...) { }
}

void main()
{
    S s;
    s.selection = 1;  // select one item
    s.selection = [1, 3];  // select multiple items
}
-----

I've found this feature to be useful in GUI-related code.
