The Lisp archiver has the directive "make-class" (in addition to
"make-instance").  This is useful when you want to load a dataset, but
the fields aren't already described by a class in the model's C code.
While there won't be class-specific methods for the classes made in
this way, you can use probes to get at the data.

But in the anl Scheme demo, it is possible to construct new methods at
runtime.  So it isn't far from the truth to say that you could have a
model archive full classes including mechanism.
