I would have to say that the 2.x behaviour of input() is a mistake
that's being corrected in 3.x. With a simple name like input(), it
should do something simple and straightforward - not eval() the
expression.

Uhhhh.... NO. NO NO NO. What if someone enters "os.exit()" as their
number? You shouldn't eval() unchecked user input!
