Can't seem to be able to output struct field values

[jagregory]

The following test fails when trying to evaluate %span= v.Val.

type testObject struct{ Val int }

func TestForArrayObjectRangeConstruct(t *testing.T) {
    scope := make(map[string]interface{})
    scope["looper"] = [5]testObject{
        testObject{4},
        testObject{-128},
        testObject{38},
        testObject{99},
        testObject{1},
    }

    expected := "<p>\n" +
        "   <span>0</span><span>4</span>\n" +
        "   <span>1</span><span>-128</span>\n" +
        "   <span>2</span><span>38</span>\n" +
        "   <span>3</span><span>99</span>\n" +
        "   <span>4</span><span>1</span>\n" +
        "</p>"
    input := "%p\n  - for i, v := range looper\n    %span= i<\n    %span= v.Val"
    engine, _ := NewEngine(input)
    output := engine.Render(scope)

    if output != expected {
        t.Errorf("Expected\n%s\nbut got\n%s\n", expected, output)
    }
}

@jagregory Thanks for finding this issue. I have made a commit to fix it. I also ensured that it works for slices, too.
