A Common Lisp example that leaves out Lispworks and Allegro Common Lisp focusing only on SBCL + emacs, as usual.

but sbcl is far more common than those two. its also free, unlike those two. i think this is ok as long as its stated cleary (and it is)

I’ve used all of these semi-extensively (slightly less so LW). The environments you get with FL and LW are useful if you aren’t an experienced Emacs user, and each of the pro ones comes with a lot of useful support (and FL’s amazing but expensive gdb), but these days, if all you want to do is get programming done, and don’t need, or don’t want to pay for a highly supported world-class engineering platform, you can do pretty much everything you want at a lot less cost and weight with sbcl, emacs, amd some calling to python. Libraries. If some multi-millionaire wanted to do the world a solid, they’d buy and open source (and pay for continuing support) for FL.

As a lifelong vi user, SLIME is useful even if you aren't an experienced emacs user.

For a while I used SLIME as my debugger and vim as my editor.

I'm inclined to try to learn a Lisp, but the tight integration with Emacs is putting me off. I spent a lot of time and effort to learn vim and I'm wondering why a family of languages should be this dependent on a specific editor...
