Review comment:
       Thanks.  Yeah, that is what I was gathering but I haven't come across an 
answer yet.  Jinja is new to me so this may be really obvious.  Does/can jinja 
magically know it should be a dict, or do I change the operator to accept type 
Union[dict, str], and if it's a string then handle the conversion inside the 
operator?
