-// About BE_FRUGAL_WITH_GUIDS
-// If this macro is set, then a GUID will NOT
-// be calculated until the first call to get_guid()
-// This also means that the node doesn't get
-// added to the database until get_guid() is called
-// for the first time, or set_guid() is called.
-// If it is expensive to calculate GUIDs, then
-// this can improve performance a tad in
-// some cases. Otherwise, it doesn't change
-// much of anything.
