Stacking generators

[Ofnuts]

Why not just return the appropriate generator:

def generator(self):
    if self.uc:
        return self.ucGenerator()
    else:
        return self.lcGenerator()

Then you're not generating over a generator, you're just providing the correct generator to the original iteration.

** Slaps forehead ** Doh... In my "factory" method I was returning self.ucGenerator and not self.ucGenerator(). These parens make a huge difference...
