Github user tillrohrmann commented on the pull request:

    Cool tool, Robert. This is definitely useful for users.
    If this tool also supported positional arguments, then we wouldn't have to
    change how the examples are called. Furthermore, it wouldn't force you to
    name all of your parameters if you don't want to.
