                     // Why this piece of insanity?  This is because most script constants are C# value types (e.g. int)
                     // rather than wrapped LSL types.  Such a script constant does not have int.Equal(LSL_Integer) code
                     // and so the comparison fails even if the LSL_Integer conceptually has the same value.

                     // However, a future better approach may be use LSL struct script constants (e.g. LSL_Integer(1)).
