Description Julien Fontanet 2009-06-15 13:09:42 UTC 
class AClass {
	private int[] _array = new int[] {1, 2, 3};

	public int[] array {
		get {return this._array;}
	}
}
var a = new AClass ();
stdout.printf ("%d\n", a.array.length);

"3" should be print on the screen, however "0" is displayed.

Here is the C code:
AClass* a;
gint _tmp0_;
a = aclass_new ();
fprintf (stdout, "%d\n", _tmp0_);

Confirming.

Comment 3 Michael 'Mickey' Lauer 2009-10-16 23:10:10 UTC 
The foreach statement seems to get this right, hence for your viewing pleasure here's the ugly workaround:

var length = 0;
foreach ( var element in array )
{
    length++;
}
Comment 4 Jürg Billeter 2009-10-17 19:43:05 UTC 
There is an easier workaround:

	var arr = a.array;
	stdout.printf ("%d\n", arr.length);
