Both the line 343 and line 423 sites do the same thing: define the class
symbol as an obsolete variable, and recommend using the quoted symbol
instead.
This is applicable to most situations where people are specifically
trying to do something with the class, but in this case (the &optional
args) the method is supposed to be doing something with the symbol-value
of a (here unquoted) symbol (I was using it wrong). I can't think of a
situation where it would make sense to be using the class symbol in this
way, so I think the proper place to raise an error is in cl-generic.el,
not in the class definitions here.

But I can't do that for everyone who's compiling EBDB locally (on
package update, etc).
