No, there is no proper use-case for it. However, please keep in mind that this code is proof of concept for testing, and a user might accidentally pass a string...

Sounds good. What would you think about defaulting the value to an empty string? Technically this use-case is not by design, so this kind of user code is a grey...

Yap, I've noticed it after commit (CRLF settings). I've fixed the commit to check the values in Ctor. This is consistent to other implementations as you specified.

Looks like you are missing the argument in the CLI or IDE. Did you manage to work it out? @HackPoint
