In that case, it is less important to me to get the different equal? behavior.

The problem: For my web-parameters, I need a mark value that can be
serialized and deserialized, will work as a mark after that process,
and will be different if the source of the program changes. I was
using procedures, because I have a way of (de)serializing them and
they are touchy about the program source. But, because of the eq? they
do not work as marks. So, I switched to a symbol. The symbol I'm using
is the deserialization-info associated with the closure struct created
for the new procedure. This is workable, but my initial inclination
was to let my closures be equal?... something I would be able to test.
