What about idea of making a "Pythonic Lisp"...i.e. a Lisp that more closely resembles the syntax of Python?

>>> sum(range(10)) == sum(reversed(range(10)))
If you actually want a reversed range, use slice notation instead of
the reversed() function, which is more parallel to iter().
>>> a = range(10)
>>> b = a[::-1]
>>> sum(a) == sum(b)
>>> sum(b) == sum(a)
Now you actually have a range that runs the other direction, instead
of an iterator that runs through the range backwards.
