Can you please increase the coverage and fix the 3 issues?

I fixed the code smells and opened an issue for the rest of the FPs that remain in the file. Regarding the coverage I could not come up with any valid or invalid code snippet that would cover the cases, however I would rather leave it there as defensive coding than to create AD0001s if anything changes in Roslyn.

It's weird because this line is tested in InfiniteRecursion.CSharp11.cs through:

public class Decrement : IDecrementOperators<Decrement>
{
    public static Decrement operator --(Decrement val) => --val; // Noncompliant
}

same for Unary:

public class BitWise : IBitwiseOperators<BitWise, BitWise, BitWise>
{
    public static BitWise operator ~(BitWise value) => ~value; // Noncompliant
    public static BitWise operator &(BitWise left, BitWise right) => left & right; // Noncompliant
    public static BitWise operator |(BitWise left, BitWise right) => left | right; // Noncompliant
    public static BitWise operator ^(BitWise left, BitWise right) => left ^ right; // Noncompliant
}

but the code coverage tool is not detecting those lines as covered.
