NEW_FEATURE = "remove_barry_from_BDFL" or
"barry_resign_as_FLUFL"/"barry_resign_as_BDFL";
Add a new future import NEW_FEATURE. This reverts the effects of the future
import "barry_as_FLUFL" easter egg IF it is ever imported. This is absolutely
unnecessary when "barry_as_FLUFL" isn't imported.
barry_as_FLUFL is a joke, not a serious feature.
Why do you want to enable it, then remove it? What's your motivation for
this feature?

It is perhaps worth considering on April 1, but not in September.

You mean `factorial` here, right? `gamma` coerces int to float before
evaluating, doesn't it?
