        value = _value;
    }
}

function testRevokePersistent() public {
    // select a specific fork
    cheats.selectFork(mainnetFork);
    
    // create a new contract that's stored in the `mainnetFork` storage
    SimpleStorageContract simple = new SimpleStorageContract();
    
    // `simple` is not marked as persistent
    assert(!cheats.isPersistent(address(simple)));
       
    // make it persistent
    cheats.makePersistent(address(simple));
    
    // ensure it is persistent
    assert(cheats.isPersistent(address(simple)));
    
    // revoke it
    cheats.revokePersistent(address(simple));
    
    // contract no longer persistent
    assert(!cheats.isPersistent(address(simple)));
