I'm not sure how useful this is ... Credulous could emit "unset AWS_ACCESS_KEY_ID" but you'd still have to eval that. It seems easier to handle this in the wrapper (if at all)

@nonspecialist I'm trying to get this functionality working, I'm leaning towards the wrapper option eval'ing the output of go command(unset creds with user variables hopefully).

Here is a gist of my current implementation(WIP) - https://github.com/kunday/credulous/compare/realestate-com-au:master...clean_option

It looks good, panic_the_err only panics if there is an error though, so you don't need the conditional around it.
