Getting rid of eval for accesing "deep" properties

Hi everyone.

I'm dealing with some javascript code which uses eval to access properties of an object.
For instance, I have the following:

var events = {};
events.flatUsers = {};
events.flatUsers.Clone = "I'm the Clone property";
events.flatUsers.Edit = "I'm the Edit property";
events.flatUsers.Delete = "I'm the Delete property";

var key = "flatUsers.Clone";

Right now, given 'events' and the key 'flatUsers.Clone', eval is used to retrieve events.flatUsers.Clone

window.alert( eval("events." + key) );

I'd like to get rid of eval, and since I cannot do just:
events[key]

I wrote the following:
function evaluate() {
var context = this;
for(var i = 0; i < arguments.length; i++) {
context = context[arguments[i]];
}
return context;
}

window.alert(evaluate.apply(events, key.split('.')));

Surely this can be improved, since I'm a newbie in Javascript. Any suggestions?
