In variable declaration, initializer should have a type that is implicitly convertible to the required type, with the exception of the case that is an unique expression.

But the rule is currently broken in struct object construction. This code should raise errors in all declarations.

void main()
{
    static struct S
    {
        int[] a;
    }
    int[] marr = [1,2,3];
    immutable int[] iarr = [1,2,3];
    // mutable object should not be implicitly convertible to immutable
    immutable S i = S(marr);
    // immutable object should not be implicitly convertible to mutable
    S m = immutable S(iarr);

    static struct MS
    {
        int[] a;
        this(int n) { a = new int[](n); }
    }
    // mutable object should not be implicitly convertible to immutable
    immutable MS i = MS(3);

    static struct IS
    {
        int[] a;
        this(int n) immutable { a = new int[](n); }
    }
    // immutable object should not be implicitly convertible to mutable
    IS m = immutable IS(3);
}
