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