-1 to the a_3. That goes against all of the slicing conventions in Python.
It is kind of a cool idea, though. I'd like some time to try it out
before committing one way or the other.
What about having a "experiment mode" in Sage that turns on things like
this? Some variable in some module somewhere that people can set to
switch on some experimental behavior so they can test it out and give
feedback. In other words, setting sage.misc.misc.EXPERIMENT_MODE=True
turns it on.
