Ok, there's no actual list yet, as far as I know. There should be.

I just meant that an expanded `define-struct' is something I'd really
like to see closer to the core language. Ryan's `define-struct*' is
very much what I had in mind, actually.

Well, I see every thread on this list as a discussion about what should
be in v4.0. :)

Don't hesitate to make specific suggestions, and we'll be sure to bring
up big things for discussion --- such as making pairs immutable and
using `#module' instead of `(module ...)'.
