regarded and expertly designed C++ library projects in the
world.

BOOST_CONTRACT_NO_OLDS — Automatically defined by this library when old value copies are not to be performed.
// In header: <boost/contract/core/config.hpp>
BOOST_CONTRACT_NO_OLDSThis library will define this macro when users define both BOOST_CONTRACT_NO_POSTCONDITIONS and BOOST_CONTRACT_NO_EXCEPTS (this macro is not a configuration macro and this library will generate a compile-time error if users try to define it directly). Users can manually program #ifndef statements in their code using this macro to completely disable compilation of old value copies or use the macros defined in boost/contract_macro.hpp (recommended only for applications where it is truly necessary to completely remove contract code compilation from production code).
