May I suggest you this variant?
def raiseStopIteration():
raise StopIteration
g = (n for n in range(100) if n*n < 50 or raiseStopIteration())
Well, there are more characters...
But it is not using any syntax changes and does not require any approval
to be functional. Yet it is as fast as the proposed variant, does not require
modules and, I hope, will not confuse you or anyone else.
