Confusing description of Tracking queries

`CsvWriter.Context.Configuration.HasHeaderRecord = false` does not work as expected

2

In previous versions, `csv.Configuration.HasHeaderRecord = false;` would prevent a CsvWriter from printing a header. In the current version, `csv.Context.Configuration.HasHeaderRecord = false;` no longer prevents a header from being printed. If...

Maybe vs C#8 Nullable Reference Types

I'm slowly starting to adopt C# 8, and I'm finding it practical to switch out Maybes for nullable reference types. I wonder if any scenarios come to mind where a...

new Result()

Perhaps a consequence of using `struct` for Result: ``` var result = new Result(); // Result._logic is null if (result.IsFailure) { } // null reference exception ```
