function $setter(obj, prop) function() obj.__lookupSetter__(prop).apply(obj, Array.prototype.slice.call(arguments));
function $getter(obj, prop) function() obj.__lookupGetter__(prop).apply(obj, Array.prototype.slice.call(arguments));

Object.prototype.getSetter = function(prop) $setter(this, prop);
Object.prototype.getGetter = function(prop) $getter(this, prop);

*Requires JavaScript 1.8*

`$[gs]etter(obj, property)` returns `function() obj.__lookup[GS]etter__(property).apply(obj, Array.prototype.slice.call(arguments))`

`object.get[GS]etter(property)` returns `$[gs]etter(this, property)`

Useful for getting the getters and setters of objects like `location`, so you can do stuff like location.getSetter("hash") to get the native hash-changing function.

Example:

    var foo = {a: 5}
    foo.__defineSetter__("bar", function(x) x/this.a)
    var fooBarSetter = foo.getSetter("bar") // $setter(foo, "bar") also works
    fooBarSetter(40) == 8
    
    var changeHash = location.getSetter("hash")
    changeHash("test")
    var getHash = location.getGetter("hash")
    getHash() == location.hash
    getHash() == "#test"
    
    function changeInnerHTML(el, html) el.getSetter("innerHTML")(html)
    changeInnerHTML(document.body, "test")
    document.getSetter("title")("Test")
