`match` should not be an iterator

I think it makes it more complicated to work with the function because in order to subscript it one has to force it into a list first. If each result had to be fetched from the server then it would make a lot of sense to yield them one by one, but since the response is already downloaded and parsed, returning all results at once makes no difference.

Start by locating the Python match function and any tests or callers that cover its return value. Confirm the requested eager-return behavior and update the relevant coverage so done means callers can subscript the result without converting it to a list.
