On the fib(20) test, it suggests using this to get a 30,000 times speed-up:
BTW while doing my tests, I found you could redefine the same function
with no error:
def fred():
pass
def fred():
pass
def fred():
pass
For classes too. I was aware you could reassign a different value to
such names, but didn't know this applied to def.
I guess the reason is that 'def' is just another statement, and
statements can be conditional, so that you can have several versions.
It was still a surprise. What an easy way for things to go wrong by
writing a new version of a function but forgetting to delete the
original. And if they happen to be in the right order so the program
still works, it must be confusing to read.
