Can I extend the console object (for rerouting the logging) in javascript?

Question

Is it possible to extend the console object?

I tried something like:

Console.prototype.log = function(msg){
    Console.prototype.log.call(msg);

// console aliases and verbose logger - console doesnt prototype
var c = console;
c.l = c.log,
c.e = c.error,
c.v = c.verbose = function() {
    if (!myclass || !myclass.verbose) // verbose switch
        return;
    var args = Array.prototype.slice.call(arguments); // toArray
    args.unshift('Verbose:');
    c.l.apply(this, args); // log
};

// you can then do
var myclass = new myClass();
myclass.prototype.verbose = false;
// generally these calls would be inside your class
c.v('1 This will NOT log as verbose == false');
c.l('2 This will log');
myclass.verbose = true;
c.v('3 This will log');

I noted that the above use of Array.prototype.unshift.call by nitesh is a better way to add the 'Verbose:' tag.
