Builder.Pop doesn't work as I would expect

[nono]

When using the Pop() method of an alt.Builder on nested objects, I would expect to close the last object and move one level up. But it doesn't seem to be the case.

Code is probably better to explain that. I have modified a test:

func TestBuilderObject(t *testing.T) {
	var b alt.Builder

	err := b.Object()
	tt.Nil(t, err, "b.Object()")
	b.Pop()
	v := b.Result()
	tt.Equal(t, map[string]interface{}{}, v)

	b.Reset()
	tt.Nil(t, b.Result(), "b.Result() after reset")

	err = b.Object()
	tt.Nil(t, err, "first b.Object()")
	err = b.Value(true, "a")
	tt.Nil(t, err, "b.Value(true, a)")

	err = b.Object("b")
	tt.Nil(t, err, "second b.Object()")
	err = b.Value(false, "c")
	tt.Nil(t, err, "b.Value(false, c)")

	b.Pop()
	err = b.Value(nil, "d")
	tt.Nil(t, err, "b.Value(nil, d)")
	b.PopAll()

	v = b.Result()
	tt.Equal(t, map[string]interface{}{"a": true, "b": map[string]interface{}{"c": false}, "d": nil}, v)
}

And running the test gives:

$ go test -run TestBuilderObject
--- FAIL: TestBuilderObject (0.00s)
    util.go:31:
        expect: (map[string]interface {}) map[a:true b:map[c:false] d:<nil>]
        actual: (map[string]interface {}) map[a:true b:map[c:false d:<nil>]]

Is it a bug or the expected behavior?

Looks like a bug to me. I'll get that fixed. I'm travelling but should be able to get to it tonight.

Please try the object-pop branch.

It has been fixed by #97
