Oh, I didn't mean to imply there's something wrong with your approach, only that there are simpler cases to convince people of the need for defensive programming. Your solution is fine for the languages you're using.

Hmm, I wonder what language it was, if not C#? I recall one of them would produce an error (and of course C++ with the warning enabled).

Point taken. As for your question, I’m not sure which language besides TS supports checking exhaustiveness. Btw, I had copied the gist link incorrectly in the solution part of the article. You can now see the use of the never type. Woopsie!

@edA-qa, in the .Net world are you thinking of F# maybe?
