I like Lisp a lot, especially Scheme. It's simple, it's pure, it's expressive, it's powerful, and it's fun to write. If I could, I would use it for most things.
I can't convince anyone to use it. They just don't like the look of it, they stumble at the brackets. I know that I can't write something in it and expect other people to use it, build it or maintain it.
Lisp advocates think that "everything looks the same" is an advantage, whereas most people strive desperately to make things look different in informative ways with syntactic features (e.g. different brackets) and syntax highlighting.
One of the reasons it has those data structures is because it sits on the JVM and to maintain compatibility with Java apps it must use them and provide a syntax for them. That’s a practical choice, of course, but also less of an idiomatic lisp.
In (pure) lisp there is only one main data structure and it’s everywhere.
If they had an actually good IDE for it that was LispWorks I would give it a go.
Forcing the overhead of learning CommonLisp, which is actually a fairly big language despite the syntax, on top of learning how to use emacs is a big ask.
I can't convince anyone to use it. They just don't like the look of it, they stumble at the brackets. I know that I can't write something in it and expect other people to use it, build it or maintain it.
So I don't use it. And nor does anyone else.
