         *
         * By returning different values from the enter and leave functions, the

         * The algorithm below finds all conflicts via making a series of comparisons
         * between fields. In order to compare as few fields as possible, this makes
         * a series of comparisons "within" sets of fields and "between" sets of fields.
         *
         * Given any selection set, a collection produces both a set of fields by
         * also including all inline fragments, as well as a list of fragments
         * referenced by fragment spreads.
         *
         * A) Each selection set represented in the document first compares "within" its
         * collected set of fields, finding any conflicts between every pair of
         * overlapping fields.
         * Note: This is the *only time* that a the fields "within" a set are compared
         * to each other. After this only fields "between" sets are compared.
         *
         * B) Also, if any fragment is referenced in a selection set, then a
         * comparison is made "between" the original set of fields and the
         * referenced fragment.
         *
         * C) Also, if multiple fragments are referenced, then comparisons
         * are made "between" each referenced fragment.
         *
         * D) When comparing "between" a set of fields and a referenced fragment, first
         * a comparison is made between each field in the original set of fields and
         * each field in the the referenced set of fields.
         *
         * E) Also, if any fragment is referenced in the referenced selection set,
         * then a comparison is made "between" the original set of fields and the
         * referenced fragment (recursively referring to step D).
         *
         * F) When comparing "between" two fragments, first a comparison is made between
         * each field in the first referenced set of fields and each field in the the
         * second referenced set of fields.
         *
         * G) Also, any fragments referenced by the first must be compared to the
         * second, and any fragments referenced by the second must be compared to the
         * first (recursively referring to step F).
         *
         * H) When comparing two fields, if both have selection sets, then a comparison
         * is made "between" both selection sets, first comparing the set of fields in
         * the first selection set with the set of fields in the second.
         *
         * I) Also, if any fragment is referenced in either selection set, then a
