Okay, I've implemented it in the development branch the "main" kernel.scm 
(though not yet in the srfi simplified implementation).

Let's try it out!

If it seems reasonable, we'll need to modify the spec, though this one's easy.  
I've added text to [Solution] to note that this might become the case.  It'd be 
version 0.5 at that point.

I think we also need to nail down the semantics for improper lists in {...} 
before we update to spec version 0.5.
