I've felt for a while that something like this would be superior to the positional way of working, in most cases. But I don't know whether this would result in an elegant system in reality, or not. What if positional were just sugar for records indexed by natural numbers?

There are some precedence in SQL. Which seems to work out ok for the most part. But then in SQL functions are not relations, and do use positional parameters, so not entirely pure either.

Som help from type/name inference might help in wiring things togetger.
