### Rules
|
|
|
|
- Strict equality for non-traversable nodes according to [egal](http://wiki.ecmascript.org/doku.php?id=harmony:egal).
|
|
- `eql(NaN, NaN).should.be.true;`
|
|
- `eql(-0, +0).should.be.false;`
|
|
- Arguments are not Arrays:
|
|
- `eql([], arguments).should.be.false;`
|
|
- `eql([], Array.prototype.slice.call(arguments)).should.be.true;`
