I agree, no unsigned values, please.
In D unsigned values are bug-prone, it's better to avoid them when possible, they are useful almost only when you need a bitfield (they are useful for arithmetic only exceptionally, when you really need a positive range larger than the signed one and you can't use a value with more bits).
