I'd like to clarify that defined generic function variables are "read
only" in the technical Dylan sense that you can't assign to them at
run-time.  This doesn't mean that you can't add new methods; method
addition is restricted only be sealing and method congruence.

Note also that a "defined generic function" variable is not any old
variable that happens to hold a generic function; I mean the GF
variables defined by define class, define generic and define method.
