```javascript
var setFunctionName = require('set-function-name');
var assert = require('assert');

const obj = {
    concise() {},
    arrow: () => {},
    named: function named() {},
    anon: function () {},
};
assert.equal(obj.concise.name, 'concise');
assert.equal(obj.arrow.name, 'arrow');
assert.equal(obj.named.name, 'named');
assert.equal(obj.anon.name, 'anon');

assert.equal(setFunctionName(obj.concise, 'brief'), obj.concise);
assert.equal(setFunctionName(obj.arrow, 'pointy'), obj.arrow);
assert.equal(setFunctionName(obj.named, ''), obj.named);
assert.equal(setFunctionName(obj.anon, 'anonymous'), obj.anon);
