compile-time initialization of objects need?

[Weed]

In fact, the D is not contain a mechanism for compile-time
initialization of objects. Maybe add?

For example, that would be very usable for any objects which have
mathematical primitives.

Example:

struct S
{
    float[10] array;

    this( float f )
    {
        array[0] = f;
    }
}

void main()
{
    S a = S(8); // ok
    static S b = S(8); // error
}
