Question: When I get an error inside a #object the REPL crashes and no command seems to escape, so I have to restart the terminal.
Ctrl + C and Ctrl + D do not work.
What kind of REPL are you running?
Note - this question originally contained multiple questions. I've broken those up into separate questions and focused this one on just the original question. Putting multiple questions into a single question fights against many of the goals and benefits of this site.
