"no-unused-vars" rule false positive in inherited contracts

I get an [ERROR] At line: x, column: y -> Variable 'someAddress' is declared but never used. in the scenario below, in which the variable is used in contracts inheriting from the base but not in the base contract itself.

contract IMyContract {

  address public someAddress;

  function myFunction(address someVariable);
}

import 'IMyContract.sol';
contract MyContract is IMyContract {
  function someOtherFunction(address X)
  {
    someAddress = X;
  }
}

this issue no longer persists since solium does not check state variables for usage any more. feel free to re-open in case you face this (or something similar).

Ahh! When I test the whole code in a single file, it doesn’t pose any errors.

You must’ve declared IMyContract in 1 file, and MyContract in another. At a time, Solium lints only a single file, so it is not informed whether you are using the variable in some other file or not.

This needs fixing.
