This method has the following declaration:
def scan(self, func, *args, **kwargs)
It means, that you can pass to 'func' any parameter except named
parameter 'reverse'.
Of course, scan() can be used to execute some operations on rows - I
think it was primary Ed's goal.
But why don't use it for something more practical, like calculations or
testing for some conditions?
It would be a pity to waste its potential.
So, we are at the beginning, how to retrieve result?
