It's still… not the same. In CL (and specially with SBCL), we get compile time (type) errors and warnings at the blink of an eye, when we compile a single function with a keystroke (typically C-c C-c in Slime).

And there's also been improvement, see Coalton for a ML on top of CL. (https://github.com/coalton-lang/coalton/) (and SBCL itself evolves)

It's pretty much impossible to explain to people what it's like to work in a CL environment.

If you’re part of the group missing something, how would you know?

I use python/C for my day job and common lisp for my wacky off the clock hacking.

I used to use scheme and racket but the joy of debugging in CL is worth putting up with two (or four) name spaces.

Curiosity beyond your own tools

I haven't used CL myself, but it wouldn't surprise me if CL does a better job. Just pointing out that Python is significantly better in this respect than it used to be. In particular, using VS Code with Pylance, I can see type errors highlighted as soon as I write the code---I don't even need to use a keystroke. 24 years ago, I don't think anything like that was possible; the language didn't even support type annotations.
