Hey hey, isn't the Python mantra that we're all adults here? It'd
be the programmers responsibility to use only code that has no
side effects. I certainly can ensure that no side-effects occur in the
following code: 1+2. I didn't even need a time machine to do that :P
Or the primitive could be implemented so that Python
throws a TimeoutException at the earliest opportunity. Then one
could write except-blocks which deal with rolling back any undesirable
side effects. (I'm not saying such timeout feature could be
implemented in
Python, but it could be made by modifying the CPython implementation)
