I often question switch statements though, I'm actually quite happy that
Guido didn't make them part of Python. Often something like this is more
appropriate:
handlers = {
500: http_ok,
404: http_not_found
}
handlers[retcode](request, response)
Of course, since we are talking performance of the GCC compiler here, I
suppose it's one of the cases where performance for a O(1) operation do
count, and then it's a different matter. All I'm saying is that most
code I see using switch statements would often be better off without it.
