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`
