How to use local reference type storage variable in Solidity 0.5.0

Question

I'm trying to understand value type and reference type concept in Solidity as per new changes. I'm trying understand local reference types with following example.

pragma solidity ^0.5.0;

contract Locations {

  function doSomething() public  {   

    uint[] storage localArray;  

  }
}

It gives me an error of array initialization. However after doing something like uint[] storage localArray = new uint[]; (which might also wrong) I found strange error

Type function (uint256) pure returns (uint256[] memory) is not implicitly convertible to expected type uint256[] storage pointer

Any thought?

You can not declare new storage variables inside functions. You can only declare new memory variables (see Storage variable inside a function)
