I imagine it's actually goops that's doing it.

Try using "define-immutable-type <foo>" and then add a (display

That's what prompted my original post, I thought it might be handy to be
able to use define-immutable-type (and the other record definitions) to
create "normal" goops class names.

So that you can have:

  (define-immutable-type foo ...)
  (define-method (bar (x <foo>)) ...)

instead of only supporting:

  (define-immutable-type <foo> ...)
  (define-method (bar (x <<foo>>)) ...)

Of course you can always just:

  (define <foo> <<foo>>)

afterward, but that's not quite right.

I could just use goops classes, but I was interested in immutability,
and at the moment they don't appear to support it.
