Hey NiceRobot, nice to see you here too :)
Comments, as you mentioned, start with # (I should document them :-P).
Agree on redirection, that’s something I’ve been thinking about but haven’t been able to crack it in my head yet.
As far as the contrived Bash example goes…you’re right, I would also use $?. The problem is if we add $? in the bash example it’s going to look even more verbose, so I didn’t want to make it “unfair”. But your point makes sense, I might change the example (actually, if you send a PR I’d be happy to merge :-P).
PS. no worries about your point of criticizing the language: when it’s out there in the open, you have to be ready for criticism, I look forward to that :)
