As mentioned in #7 and #6, REPL should support using !! to refer to the previous command. This specifically relates to #6, as the work being done for that (having a history of commands) means that substituting !! for the previous command should be easy.

Actually, upon further thought, I'm not sure when in the process Bash substitutes !! for the previous command — it's possible it's not parsed in strings, which we'd want to mimic. My point is that I don't think it's as easy as a flat-out find&replace.

upon even more thought, especially since i don't think it will be easy to add things to the bash history, we can just substitute !! on our own using the commands you've entered in REPL
