Those are really good counterexamples and I love your points.

However... just kidding, there's no "however." Great reply.

    You can get away with that if you're writing 
    something for immediate delivery, 

I've worked on some big Rails monoliths and this just wasn't an issue very often.

But as you say, I think library code is another story.

Incidentally, whether library or application code, I've found that keyword arguments with well-chosen names have reduced this problem even further. It's not clear that `do_something("blue")` is incorrect, but `do_something(user_age: "blue")` is self-evidently bad.
