Apparently, there's been a big brouhaha over whether or not Python needs tail-call optimization (TCO). This came to a head when someone shipped Guido a copy of SICP, because he didn't "get it." I'm in the same boat as Guido. I understand the concept of tail-call optimization. I just can't think of any reason why Python really needs it.
To make this easier for me to understand, what would be a snippet of code that would be greatly simplified using TCO?
