[Vala] Trouble with array length in vala 0.7.4

[Sam Danielson <samdanielson gmail com>]

I am having trouble with arrays in expressions. AFAICT foo.x.length
doesn't work if x is a function or property returning an array. I
explain more in the comments of the following snippet. I couldn't find
a bug matching this exact behavior but I would like to know if anyone
else has come across this before I file it. Using 0.7.4.

void main () {
        var foo = new Foo ();

        // This prints the correct value, 4.
        print ("    a: %d\n", foo.a.length);

        // These print incorrect results. Lengths are uninitialized.
        print ("aprop: %d\n", foo.aprop.length);
        print ("afunc: %d\n", foo.afunc ().length);

        // Assignment to a temp variable. Correct again, 4.
        var tmp2 = foo.afunc();
        print ("afunc: %d\n", tmp2.length);
        var tmp1 = foo.aprop;
        print ("aprop: %d\n", tmp1.length);
}

class Foo {
        public int[] a = {1,2,3,4};
        public int[] aprop {
                get { return a; }
        }
        public int[] afunc () {
                return a;
        }
}
