Questions about initialization of array of objects

[Andrey]

I'm not sure about proper understanding of RAII idiom, but should 
objects in array be automatically constructed during array 
initialization?

Example.
class ClassPoint {
    int x,y;
}

struct StructPoint {
    int x,y;
}

ClassPoint[8] arr; //static array of null references;
StructPoint[8] arr2;

arr[0].x=1 //error, there is no object
arr2[0].x=1 //OK.

Here I have two questions:

1) Can you have automatically constructed objects with default 
class constructor?
2) Can you setup memory attributes for static array using 
core.memory functions, say, to force GC not to scan this portion 
of memory during collection?
