Unused variables warning in address.call return tuple (bool, bytes memory)












2















I have the following code fragment.



function forward(address destination, bytes memory data) public { 
(bool res, bytes memory retData) = destination.call(data);
assert(res);
}


Since retData is not used, I am getting the following warning (compiled with solidity 0.5.0):



Compilation warnings encountered:

/Users/ivica/Documents/deka/hekate.reloaded/digits-node/contracts/IdentityProxy.sol:55:20:
Warning: Unused local variable.
(bool res, bytes memory retData) = destination.call(data);
^------------------^


Question: how to get rid of it?

          Does this work for you?



          pragma solidity ^0.5.2;

          contract Test {

          function forward(address destination, bytes memory data) public {
          (bool res, ) = destination.call(data);
          assert(res);
          }
          }


          Basically we are omitting the second assignment.
