Miscellaneous 0.8.0 stuff

[oscbyspro]

I'll use this thread to document various minor changes.

[oscbyspro]

Lots of fuzzing. It's nice. Haven't found any bugs yet.

[oscbyspro]

• I'll replace plus (_: Bool) and incremented() with incremented(_: Bool).
• l'll replace minus(_: Bool) and decremented() with decremented(_: Bool).

[oscbyspro]

I'll add BinaryInteger/isPositive because arbitrary integers can do better than x > 0.

extension BinaryInteger {

    /// Indicates whether this value is greater than zero.
    ///
    /// - Note: Big integers evaluate it in place, cf. `compared(to: 0)`.
    ///
    @inlinable public var isPositive: Bool {
        if !Self.isArbitrary {
            return self > Self.zero
            
        }   else if Bool(self.appendix) {
            return !Self.isSigned
            
        }   else {
            return self.withUnsafeBinaryIntegerBody {
                !$0.isZero
            }
        }
    }
}

Note

Req. arbitrary integer normalization (#26) might be useful here too.
