// Emulate the API of APC, over APCU
// Note: for PHP < 7, this compatibility used to be provided by APCU itself (if compiled with some options)
//       for PHP 7+, it can be provided by the mean of apcu_bc, which is not so simple to install
//       The current emulation aims at skipping this complexity
