What is best way to get see function from separate file

[Suliman via Digitalmars-d-learn]

Sorry for wrong posting!

I have got logger instance in App.d

void main()
{
...
  FileLogger fLogger = new FileLogger("ErrorLog.txt");
  foo();
}

utils.d:
foo()
{
// I need logging here
}

Also I have file utils.d that include stand-alone functions that 
is not in classes. In one of them I need to implement logging.

What is the best way to do it. I see only two way -- create new 
Loggining instance. And second -- to import App.d as module, 
because without importing I would not able to see Logger instance.

But both of this way is look ugly. Is there any best solution?
