 Error position: <['_dummy']; _dummy = _this call compile >
 Error Missing ;
Error in expression <

disableSerialization;
   private "_data";     _data = if (((typeName (_this)>
 Error position: <"_data";     _data = if (((typeName (_this)>
 Error Missing ;
Error in expression <

Error in expression < private ["_dummy"]; _dummy = ["Unload", _this] c>
 Error position: <["_dummy"]; _dummy = ["Unload", _this] c>
 Error Missing ;
Error in expression < private ["_dummy"]; _dummy = ["Unload", _this] c>
 Error position: <["_dummy"]; _dummy = ["Unload", _this] c>
 Error Missing ;
