The thing that happens to me is that I'll get something working in the REPL, then try to deploy it and it breaks—because unbeknownst to me, I had gotten my REPL into some state where everything was working, but a cold start doesn't look the same.

Is this a skill issue? Absolutely. Do I still restart the REPL frequently (not after every def, but often) just to make sure I'm working with the same environment my program will be experiencing at run time? Yes I absolutely do.

Ah yeah, been there, and probably the first time was when renaming a function but missing to update callers, so callers keep calling the old function, and you have no idea why the changes you made in the new function aren't working.

I have a this little function for clearing the current namespace that I call every time I rename any var inside a namespace:

  (defn clear-ns []
    (map #(ns-unmap *ns* %) (keys (ns-interns *ns*))))

Not a perfect solution, but personally I also don't know a better solution that doesn't involve loosing out on other (non-negotiable for me) benefits.

Couldn't you have one test that requires your -main and runs it?

Just fire that off every now and then?

Basically the same thing, but you don't lose repl state
