+// Short version:
+//  *Never* reorder or delete entries in the |HistogramValue| enumeration.
+//  When creating a new extension function, add a new entry at the end of the
+//  enum, just prior to ENUM_BOUNDARY.
+//
+// Long version:
+//  This enumeration is used to associate a unique integer value to each
+//  extension function so that their usage can be recorded in histogram charts.
+//  Given we want the values recorded in the these charts to remain stable over
+//  time for comparison purposes, once an entry has been added to the
+//  enumeration, it should never be removed or moved to another spot in the
+//  enum.
+//
+//  Here are instructions how to manage entries depending on what you are trying
+//  to achieve.
+//
+//  1) Creating a new extension function:
+//
+//      Add a new entry at the end of the |HistogramValue| enum. The name of the
+//      entry should follow this algorithm:
+//      a) Take the string value passed as first argument to
+//         DECLARE_EXTENSION_FUNCTION.
+//      b) Replace '.' with '_'.
+//      c) Make all letters uppercase.
+//
+//      Example: "tabs.create" -> TABS_CREATE
+//
+//  2) Deleting an existing function:
+//
+//      Given an existing entry should *never* be removed from this enumeration,
+//      it is recommended to add a "DELETED_" prefix to the existing entry.
+//
+//  3) Renaming an existing function:
+//
+//      There are 2 options, depending if you want to keep accruing data in the
+//      *existing* histogram stream or in a *new* one.
+//
+//      a) If you want keep recording usages of the extension function in the
+//         *existing* histogram stream, simply rename the enum entry to match
+//         the new extension function name, following the same naming rule as
+//         mentioned in 1). The enum entry will keep the same underlying integer
+//         value, so the same histogram stream will be used for recording
+//         usages.
+//
+//      b) If you want start recording usages of the extension function to in a
+//         *new* histogram stream, follow the instructions in step 1) and 2)
+//         above. This will effectively deprecate the old histogram stream and
+//         creates a new one for the new function name.
