When I read “I feel like I'm fundamentally missing something about iterative development in Common Lisp” in the GP, I thought of exactly what’s in these replies. I’ve only recently started learning CL via Practical Common Lisp, and while I liked Emacs+SLIME, I’m a vim guy (I know) and switched to vim+VLIME instead, and so far I’m loving it. This to me has actually been the “secret sauce” of Lisp in my early experience, because now when I go to write code or use the REPL for languages like Python and Ruby, I find myself missing the SLIME/VLIME experience. I find it to be a very intuitive and efficient way to write code interactively.
Any chance you could drop the Common Lisp equivalent of the Python program in the original post here? That is, the code that goes in Vim, then what commands or key bindings you use to execute and find the "add two lists" syntax error.
