String reference to function?

Is there a way to create a string from the name of a function? This is probably not a very descriptive question, sorry, but ultimately what I’m looking for is this:

function foobar():void {
    trace(maybe(someArg));  // foobar
}
function another():void {
    trace(maybe(someOtherArg));  // another
}
function maybe(arg):String {
     return [do something here];
}

So I’m looking for what maybe() would do, or of course a more compact technique if possible.

Thanks!
