See how long it takes you to set up a Common Lisp implementation from scratch. Eg steel bank. Better yet, watch a kid try it on for size. Land of Lisp isn’t all bad but they can’t limit themselves to just one!
Brackets are beside the point.
If a 3 year old has trouble using a hammer, you wouldn't conclude that hammers are difficult to use.
On the other hand if you don't care that's perfectly reasonable and there's not much to talk about.
sbcl —script hello.lisp
Compare that experience to choosing python. Forget the actual language just all the overhead. It's not a close run thing no matter how angry common lispers get about it.
This is my exact experience of common lisp. People aggressively pretend there's no problem other than other people are stupid and have broken minds because they didn't get functional early enough and so on.
Land of Lisp at least tried, right? And did a vastly better job than anything else I've seen. Couldn't manage to do it all on sbcl though, huh? That's a shame, isn't it? Why do you think the best effort failed in something like that?
Now do mac.
Now do windows.
Installation is only step /one/ in smashing out your first ten exercises.
Pretending something is easy because you want it to be does not make it so for others.
