> in Scheme you can redefine `define` to be number 5.

This is like asking "what if your coworker named all errs as `ok`" so everything was `if ok { return errors.New("Not ok!!"); }`. It's possible but no one does it.

This is why `defmacro` and `gensym` in common lisp are awesome, and similarly why Go's warts don't matter. Much of programming language ugliness is an "impact x frequency" calculation, rather than one or the other.

It's also why javascript is so terrible, you run into it's warts constantly all day long.

"No one does it" is extremely relative. Take your closing remark about JavaScript: I don't run into JS warts very often at all, and I'm a professional web developer who works in it day in and day out. I guess my team just doesn't do dumb JS stuff?

But apparently lots of other people do run into them regularly, so I believe that such things do exist.

By the same token, I've heard countless reports of people struggling with the flexibility that Lisp offers, with co-workers who abuse it to create nightmarish situations. That you haven't experienced that doesn't mean no one does.

ah you misunderstand me.

I don't mean "do dumb stuff", I mean I've literally never seen anyone redefine the `define` keyword in any code.

With javascript, I do see people use `===` frequently. It's a wart of the language that the operator even exist. It's not "dumb" to use it - it's how frequently are you assaulted with the bugs of the language (not bugs in your code).

That’s true but I think if a major issue is having to type === instead of == then you’re probably doing okay.
I would definitely recommend mature teams for powerful languages, and the other way around.

You wouldn't let a child handle a chainsaw.
