| // JavaScript objects [ECMA-262], DOMString [WEBIDL], Date [ECMA-262] or float |
| // [WEBIDL]. However Arrays are only valid keys if every item in the array is |
| // defined and is a valid key (i.e. sparse arrays can not be valid keys) and if |
| // the Array doesn't directly or indirectly contain itself. Any non-numeric |
| // properties are ignored, and thus does not affect whether the Array is a valid |
| // key. Additionally, if the value is of type float, it is only a valid key if |
| // it is not NaN, and if the value is of type Date it is only a valid key if its |
| // [[PrimitiveValue]] internal property, as defined by [ECMA-262], is not NaN." |
| |
| // What is required is to ensure that an Lists in the key are actually |
| // JavaScript arrays, and any Dates are JavaScript Dates. |
