Is this an arguments object? It's a harder question than you think.

Example

```js var isArguments = require('is-arguments'); var assert = require('assert');

assert.equal(isArguments({}), false); assert.equal(isArguments([]), false); (function () { assert.equal(isArguments(arguments), true); }()) ```

Caveats

If you have modified an actual arguments object by giving it a Symbol.toStringTag property, then this package will return false.

Tests

Simply clone the repo, npm install, and run npm test
