* | |
* Note that this DOES NOT SUPPORT many documented jQuery | |
* features in exchange for its smaller size: | |
* | |
* Attribute not equal selector | |
* Positional selectors (:first; :eq(n); :odd; etc.) | |
* Type selectors (:input; :checkbox; :button; etc.) | |
* State-based selectors (:animated; :visible; :hidden; etc.) | |
* :has(selector) | |
* :not(complex selector) | |
* custom selectors via Sizzle extensions | |
* Leading combinators (e.g., $collection.find("> *")) | |
* Reliable functionality on XML fragments | |
* Requiring all parts of a selector to match elements under context | |
* (e.g., $div.find("div > *") now matches children of $div) | |
* Matching against non-elements | |
* Reliable sorting of disconnected nodes | |
* querySelectorAll bug fixes (e.g., unreliable :focus on WebKit) | |
* | |
* If any of these are unacceptable tradeoffs, either use Sizzle or | |
* customize this stub for the project's specific needs. | |

Implementation Summary | |
1. Enforce API surface and semantic compatibility with 1.9.x branch | |
2. Improve the module's maintainability by reducing the storage | |
paths to a single mechanism. | |
3. Use the same single mechanism to support "private" and "user" data. | |
4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData) | |
5. Avoid exposing implementation details on user objects (eg. expando properties) | |
6. Provide a clear path for implementation upgrade to WeakMap in 2014 | |
