A languages syntax and its error messages are its user interface. Yes you can have a good tool that you don’t enjoy looking at. You can also have a good tool that’s frustrating to learn because its user interface isn’t clear and doesn’t do what you expect. Can I not hope for something that does what I need, is easy to use, and looks good?

I dislike the “you can change the syntax” argument because that just doesn’t happen. Closest thing is a new language that compiles to another.
