The R5RS reads (info "(r5rs) Equivalence predicates"):
Since it is an error to modify constant objects (those returned by
literal expressions), implementations are permitted, though not
required, to share structure between constants where appropriate.
And then, these examples:
(eq? '(a) '(a)) ==> _unspecified_
(eq? "a" "a") ==> _unspecified_
(eq? "" "") ==> _unspecified_
So no problem here, AFAICS.
