1. ArgumentNullException, 2. ArgumentException and 5. ArgumentOutOfRangeException shows how badly C# needs more ability to specify/enforce contracts.
It's awesome that C# 8 will address the number 1 problem, with non nullable references but number 2 won't be addressed until records post C# 8 by the looks of things and number 5 not until exhaustive pattern matching which doesn't look to be on the cards at all AFAIK.
