I know this is disappointing, but in this case I agree with Jelle -- this particular idea does not fit well in Python's design, it looks like an attempt at saving one opcode (or a few characters to type) for a relatively rare use case.

However, I recommend that you don't give up! There are many ways Python can still use improvement, and a few more attempts will help you calibrate your ideas with what might be acceptable.

I would also like to remind various other posters that sarcasm is *not* a good way to welcome newbies. The name of the list is python-ideas, not python-ideas-to-shoot-down-sarcastically.
