Haven't tried it but off the top of my head you could do something like:
Console.log = Console.log.wrap( function( proceed ){
var args =
$A( arguments ).collect( function( arg ){
return arg.toString === Object.prototype.toString?
JSON.stringify(object) : arg;
});
return proceed.call( Console, args );
});
You should try the Firebug console btw, it gives an interactive, explorable
version of the object rather than converting it to a String. In this case I
think giving a JSON Object.toString is a problem because the console already
gives that information anyway so now it is trying to give it twice.
