__A Volume Bump__
```js
// creates custom identity thunk
const isAnArrayOfTwo = ifd({
  // if isAnArryOfTwo does not met identity
  // then we want to return false as the default value
  default: false,
  identity: function (val) {
    return Array.isArray(val) && val.length === 2;
  }
});


// lazy evaluation of arguments
const foo = ifd(
  [[isAnArrayOfTwo, false, true, 0, [2]], 'Not Me!'],
  [[isAnArrayOfTwo, [2, 3, 4], false, 'not-an-array'], 'Or Me Either!'],
  [[isAnArrayOfTwo, undefined, [1, 2], null, [2]], 'Pick Me, And Return This String'],
  [[isAnArrayOfTwo, null, []], 'will not be evaluated']
);
