The following code:

Results in (without any warning(s)):
johnstone -11
However you choose to look at it, this means -11 > 0
(regardless of all arguments concerning implicit conversions,
1's and 2's complements, being efficient, etc).
The language should not allow unary unsigned anything.
This is unlikely to get fixed, just due to the nature of D's
philosophy when it comes to C compatibility.
It would also break a lot of existing code.
