Spew:

(plans.Map) {
 Expression: (expressions.Object) {
  Extend: (bool) false,
  Expressions: (map[string]expressions.Expression) (len=3) {
   (string) (len=3) "_id": (expressions.Attribute) {
    Name: (string) (len=3) "_id"
   },
   (string) (len=4) "name": (expressions.Attribute) {
    Name: (string) (len=4) "name"
   },
   (string) (len=6) "deeply": (expressions.Apply) {
    LHS: (expressions.Attribute) {
     Name: (string) (len=6) "deeply"
    },
    Expression: (*expressions.Object)(0xc4203eb1d0)({

Notice *expressions.Object in Spew, where Litter has only expressions.Object.
