Just test it. After the generator is terminated, no one will call range(100).next() method, if I really understand you. Maybe (as suggested before with 'if ... else break`) we should rename function raiseStopIteration() to else_break(), since it looks to me being a 'if ... else break's implementation with functions. Example will look like g = (n for n in range(100) if n*n < 50 or else_break()) That's to the matter of taste, I think. -- Alexey G.
