Overloading parent method

[GoogleCodeExporter]

Why i can't do something like this:

/** @constructor */
function Foo() {}

/**
 * @param {string} a
 * @return {string}
 */
Foo.prototype.get = function (a) { return ''; }

/**
 * @constructor
 * @extends {Foo}
 */
function Foo2() {}

/**
 * @override
 * @param {number} b
 */
Foo2.prototype.get = function (a, b) { return ''; }

***

Warning: JSC_HIDDEN_SUPERCLASS_PROPERTY_MISMATCH: mismatch of the get property 
type and the type of the property it overrides from superclass Foo.

***

I think it's strange behavior. Also, i can't override parent parameters.

/** @constructor */
function Foo() {}

/**
 * @param {string} a
 * @return {string}
 */
Foo.prototype.get = function (a) { return ''; }

/**
 * @constructor
 * @extends {Foo}
 */
function Foo2() {}

/**
 * @override
 * @param {number} a
 */
Foo2.prototype.get = function (a) { return ''; }
