Re: Two questions about eq

1) The HS says that
(eq (cons 'a 'b) (cons 'a 'b))
always returns false but
(eq '(a . b) '(a . b))
might be true. Why is this ?
Because '(a . b) is a literal object (and should not be modified), a
compiler might make both references of them point to the same cons.
2) Under what (realistic) circumstances might
(eq 1 1) be false ?
An implementation could create two different 1 objects. According to
Cliki at least, in ABCL EQL fixnums are not EQ. (I'm having trouble
duplicating that though).
