How does Genera differ from TAILP-NIL:T?
Genera uses EQ, the proposal uses EQL (maybe you didn't notice that).
Since I don't believe EQ belongs in Common Lisp in the first place, I
agree that any system function that uses EQ as a test is wrong and
should be using EQL, which is why I support the proposal. (EQ is only
in Common Lisp as a concession to implementors who haven't figured out
how to implement EQL efficiently (it isn't hard), or hadn't figured it
out yet in 1984).
