Title: Two variables with their `.toString()` equal may not be the same value.

function proxy(fn) {
return function () {
fn();
}
};
var a = proxy(function () {
alert('a');
});
var b = proxy(function () {
alert('b');
});
var $body = $(document.body);
$body.on('click', a).on('click', b);
// Both listener will work.
$body.off('click', a);
// Both listener will be mistakenly removed.
