Very nice that you can debug functions in the repl and set breakpoints:<p><a href="https:&#x2F;&#x2F;swift.org&#x2F;lldb&#x2F;#why-combine-the-repl-and-debugger" rel="nofollow">https:&#x2F;&#x2F;swift.org&#x2F;lldb&#x2F;#why-combine-the-repl-and-debugger</a><p>I don&#x27;t know any other repl that can do that. I know you can debug in (some) lisps and smalltalk, but I don&#x27;t know if you can set breakpoints too. Still a nice and welcome feature.
