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...
this module is legen...
