Using emit vs calling a signal as if it's a regular function in Qt
... having the 'syntactic sugar' in this case just confuses the novice (or at least me when I was a novice Qt user) - it appears that something magical or important is happening with the emit pseudo-keyword, when it does nothing at all - all the magic happens in a regular old function that moc creates ...
