Edit: or you're saying jo should always consider 0 true and 1 false to match shell return code conventions?
It was merely an observation. Of course, one can simply negate the value before passing it to jo.
jo looked as though it was for use in the shell though, so I was curious as to the design decision here.
I think it makes sense how it is, since if I typed "success@1" I wouldn't expect that to output "{success: false}" but I definitely appreciate your point about a case like "success@$?".

What's the shortest way to do that? This?
echo success@$(test $? -ne 0; echo $?) $ false; echo success@$((! $?))
success@0
