Sadly this seems to be the proper usage of raw_input when dealing with the end of the stream of input from piped input. I guess the strongly-typed, unit-testing, check-for-every-null software developer in me cringes at the idea of using exceptions under normal usage circumstances. In pretty much every other development platform, using exceptions are reserved for when things Really Go Wrong.
Oh well, Python can't be perfect in every way.
