Properly implemented, it would use the time
machine module to find every feature that will
ever be implemented in Python. So once you had
updated your code to be compatible with all of
them, it would *never* break again!

The neat thing is that it would take just one
use of the time machine to backport this feature,
and it would then bootstrap itself into existence.
