   bad side-effects. (@hax)

 - Cleaned up Function.prototype.bind with more fixes and tests from
   @bryanforbes.

1.2.8
 - Actually fixed problems with Function.prototype.bind, and regressions
   from 1.2.7 (@bryanforbes, @jdalton #36)

1.2.7 - REGRESSED

   (@jdalton #36)

 - Added support for accessor properties where possible (which is all browsers
   except IE).
 - Stop exposing bound function's (that are returned by
   `Function.prototype.bind`) internal properties (`bound, boundTo, boundArgs`)
   as in some cases (when using facade objects for example) capabilities of the
   enclosed functions will be leaked.
 - `Object.create` now explicitly sets `__proto__` property to guarantee
   correct behavior of `Object.getPrototypeOf`'s on all objects created using
   `Object.create`.
 - Switched to `===` from `==` where possible as it's slightly faster on older
   browsers that are target of this lib.
 - Added names to all anonymous functions to have a better stack traces.

1.0.0
 - fixed Date.toISODate, using UTC accessors, as in
   http://code.google.com/p/v8/source/browse/trunk/src/date.js?r=6120#986
