Unfortunately you're right. If you specify hash as a type, kafo will crash when it loads the doc. What's worse, if you don't specify type it will treat it as a string. It's not hard to add new type but for hash I'm not sure how hard it will be to add support for CLI and wizard to enter hashes. Maybe something like ```kafo --paramname key1:value1 --paramname key2:value2``` would work? @agx would you be willing to write such patch? I could give some hints maybe.
