This seems both useful and straightforward to implement and understand. I've 
attached a patch (lacking documentation but otherwise complete) -- is it what 
you had in mind?

Your wish has been granted! It already works that way, it's just not very well 
documented. Try it.

It's not a bad suggestion, but since this is Calc, nothing is very simple. 
Let's give it some thought.
