A linguistics professor was lecturing to his class one day. "In English," he said, "A double negative forms a positive. In some languages, though, such as Russian, a double negative is still a negative. However, there is no language wherein a double positive can form a negative." A voice from the back of the room piped up, "Yeah, yeah."
English is quite the merry language with this. (Reversing the meaning of "merry", ho-ho!)
It's also why D doesn't support ! in version, and why I'm a strong advocate of not having negated features.
Of course, D has "no-throw" and "im-mutable". Arggh.
