Arrays, copied or referenced?

[Audun Wilhelmsen]

Hey..

Take this code: 
--------------------------
import std.stdio;

int[] arrayTest(int[] a) {
	a.length = 5;
	a[4] = 42;
	return a;
}

int main(char[][] args) {
	int[10] foobar;
	foobar[4] = 2;
	arrayTest(foobar);
	writefln("%d", foobar[4]);
        return 0;
}
--------------------------
It prints out "42".
Now replace the line "a.length = 20", and it prints out "2".

Is that the way it's supposed to behave?
