	console.log("...wait for it...");
	if ( time > 3 ){

			console.log("...dary");
			callback(null, "legendary!");

	} else {
		callback("need more patience");
	}
};

var waitFor = function(time){
	return function(callback) {
		waitForIt(time, callback);
	}
}

TRY( "waiting for it", waitFor(5),  console.log, function(result){
	console.log("This module is " + result);
})

var dontWait = function(callback){
	TRY( "pretending to wait for it", waitFor(2),  callback, function(result){
		console.log("This module is " + result);
	});
}

var logError = function(error){
	console.log("[ERROR] " + error);
}
TRY( "not waiting for it", dontWait,  logError, function(result){
	console.log("This module is " + result);
})

will output

this module is legen...
...wait for it...
