Forgot to add: multiple threads ... multiple DBs ... multiple topics on more than one kind of message queue ... hitting and serving REST endpoints -- all no problem for the REPL and the debugger[0].

If the thing was in Java, each fix attempt would mean waiting for startup and state re-creation. And each successful debug could have meant multiple sessions (vs visiting any mix of spots in a single recording)
