As long as 1) the name can't be reassigned (like None) and 2) the
compiler is able to optimize it out when used by itself as a statement
(to avoid incurring the expense of a common but pointless name
lookup), then I kind of agree.  The added complexity of those two
restrictions detracts a bit from the appeal to elegance, though.
