That leads me to wonder what exactly the rationale for generator expressions is. The PEP says that "time, clarity, and memory are conserved by using an generator expression" but I can only see how memory is conserved.

I've been skimming due to being out of town and catching up, but I haven't seen a direct response to Jeremy's question about the rationale.
