 // Given an old enum class, add become mappings from old values to new values.
 // Some notes about how we reload enums below:
 //
 // When an enum is reloaded the following three things can happen, possibly
 // simultaneously.
 //
 // 1) A new enum value is added.
 //   This case is handled automatically.
 // 2) Enum values are reordered.
 //   We pair old and new enums and the old enums 'become' the new ones so
-//   the ordering is always correct (i.e. enum indicies match slots in values
+//   the ordering is always correct (i.e. enum indices match slots in values
 //   array)
 // 3) An existing enum value is removed.
 //   Each enum class has a canonical 'deleted' enum sentinel instance.
 //   When an enum value is deleted, we 'become' all references to the 'deleted'
 //   sentinel value. The index value is -1.
