Detect non-native ES5 shims and fall back to our own. This avoids potential issues with libraries that shim native objects with broken implementations, like older Prototype and MooTools, and certain Twitter widgets. The technique used to detect native methods isn't perfect, but works in all modern browsers and has minimal consequences if it fails.

Y.Object.isEmpty() now casts the given value to an object. This prevents exceptions when it's given a non-object, which is closer to how it behaved pre-3.4.0.

Y.Object.keys() workaround for browsers that enumerate "prototype". The non-native fallback implementation of `Y.Object.keys()` now contains a workaround for buggy browsers (like Opera 11.50) that treat function `prototype` properties as enumerable in violation of the ES5 spec. This fixes failing tests in those browsers.

Ensure that Y.Object.size() returns 0 for non-objects. Fixes #2531069 This was the behavior prior to 3.4.0, but regressed in 3.4.0 due to Y.Object.size()'s new dependency on Y.Object.keys().

Exclude 'constructor' from the list of properties we force IE to enumerate. This was causing the native constructor property to be enumerated even when it shouldn't be.

Expose _hasEnumBug and _forceEnum as protected properties of Y.Object.

Check that the window exists before looking for stuff on it. Because we <3 server-side JS!

Improve API docs and readability.

Refactor values(), size(), and isEmpty() to use keys().

Use native Object.keys when available; handle IE DontEnum keys in the shim. [Fixes #2529986] See the following URLs for details on why it's necessary to force IE to enumerate certain properties that it wrongly thinks shouldn't be enumerable: - https://developer.mozilla.org/en/ECMAScript_DontEnum_attribute#JScript_DontEnum_Bug - http://whattheheadsaid.com/2010/10/a-safer-object-keys-compatibility-implementation

Use native Object.create() if available; safer hasOwnProperty() check in owns(). When Object.create exists and neither MooTools or Prototype are on the page, we wrap the native Object.create. Wrapping instead of aliasing allows us to discard the second argument (properties) to Object.create, which we currently don't support in our non-native fallback implementation. This will ensure consistent API behavior until we add a safe fallback. Also modified owns() to use Object.prototype.hasOwnProperty() instead of relying on hasOwnProperty() on the passed object, since it may have been overridden.

Reverted detection of native Object static methods because it picks up broken implementations of these functions in MooTools and Prototype.

Uses native Object.keys/values/size when available

Y.Object() optimization -- uses cached throwaway function and will use native Object.create() if available.

'owns' tests for the hasOwnProperty method

Y.Object cleanup

leaving in owns as an alias for hasKey

moved hasOwnProperty check so that Y.Object.size works right when some messes around with Object.prototype [fixes #2528467].

getValue returns undefined if source isn't an object [fixes #2528347].

Added Object.some(), Y.some()

Any given object is only cloned once. DOM element attributes are not cloned. [bug #2528250].

API update for each/some methods [fixes #2528213].

queue-base is now part of yui-base. queue-run and queue-promote are independent modules.
