"add lots of taxes" - How incredibly naive. Any tax money would be wasted. Some people would pay more, some corrupt people will find a way to spend that tax money, and almost nothing else would change.

Well maybe, you'll make it so poor people can't drive or cool their houses in the summer, but the middle class and up won't change their behavior.

I wish you "just tax it" people would hold your electives accountable for spending before you throw more money at them.

Funny that. In my head, I parsed it as two (odd) statements under one if statement. More like when than if.

I'm not much for Common Lisp, but I do think Scheme is the prettiest language in which people write ugly code. As such, while I am sympathetic to the virtues of s-expressions, this example is not going to win any hearts or minds. I don't much care for Python's performance or newer features, but your snippet screams for a comparison:

    if condition:
        a, b, c = c, a, b
        a, c, b = b, a, c

That really seems much more clear than the gymnastics my mind has to do manually pairing the assignments inside of psetf. I won't argue that it's objectively better syntax, but I still think it is.
