// __USE_VALUES_H__           : use <values.h> header file 
// __NO_TEMPLATE_ARG_BASE__   : template arguments may not be used as base class
// __NO_FUNCTEMP_DEF_ARGS__   : function templates may not have default args
// __NO_EXPLICIT_DESTRUCTION__: no explicit destructor call
// __NO_CAST_TO_LOCAL_TYPE__  : no casting to a local type of a class
