+       * 
+       * Ids are separated into unsorted bags according to their vote weight. This specifies the
+       * thresholds separating the bags. An id's bag is the largest bag for which the id's weight
+       * is less than or equal to its upper threshold.
+       * 
+       * When ids are iterated, higher bags are iterated completely before lower bags. This means
+       * that iteration is _semi-sorted_: ids of higher weight tend to come before ids of lower
+       * weight, but peer ids within a particular bag are sorted in insertion order.
+       * 
+       * # Expressing the constant
+       * 
+       * This constant must be sorted in strictly increasing order. Duplicate items are not
+       * permitted.
+       * 
+       * There is an implied upper limit of `VoteWeight::MAX`; that value does not need to be
+       * specified within the bag. For any two threshold lists, if one ends with
+       * `VoteWeight::MAX`, the other one does not, and they are otherwise equal, the two lists
+       * will behave identically.
+       * 
+       * # Calculation
+       * 
+       * It is recommended to generate the set of thresholds in a geometric series, such that
+       * there exists some constant ratio such that `threshold[k + 1] == (threshold[k] *
+       * constant_ratio).max(threshold[k] + 1)` for all `k`.
+       * 
+       * The helpers in the `/utils/frame/generate-bags` module can simplify this calculation.
+       * 
+       * # Examples
+       * 
+       * - If `BagThresholds::get().is_empty()`, then all ids are put into the same bag, and
+       * iteration is strictly in insertion order.
+       * - If `BagThresholds::get().len() == 64`, and the thresholds are determined according to
+       * the procedure given above, then the constant ratio is equal to 2.
+       * - If `BagThresholds::get().len() == 200`, and the thresholds are determined according to
+       * the procedure given above, then the constant ratio is approximately equal to 1.248.
+       * - If the threshold list begins `[1, 2, 3, ...]`, then an id with weight 0 or 1 will fall
+       * into bag 0, an id with weight 2 will fall into bag 1, etc.
+       * 
+       * # Migration
+       * 
+       * In the event that this list ever changes, a copy of the old bags list must be retained.
+       * With that `List::migrate` can be called, which will perform the appropriate migration.
