-/**
- * Partially applies this function to a particular "this object" and zero or
- * more arguments. The result is a new function with some arguments of the first
- * function pre-filled and the value of |this| "pre-specified".
- *
- * Remaining arguments specified at call-time are appended to the pre-
- * specified ones.
- *
- * Also see: partial().
- *
- * Note that bind and partial are optimized such that repeated calls to it do
- * not create more than one function object, so there is no additional cost for
- * something like:
- *
- * var g = bind(f, obj);
- * var h = partial(g, 1, 2, 3);
- * var k = partial(h, a, b, c);
- *
- * Usage:
- * var barMethBound = bind(myFunction, myObj, "arg1", "arg2");
- * barMethBound("arg3", "arg4");
- *
- * @param self {Object} Specifies the object which |this| should point to
- * when the function is run. If the value is null or undefined, it will default
- * to the global object.
- *
- * @returns {Function} A partially-applied form of the function bind() was
- * invoked as a method of.
