Hi Joel,

IMHO this is a bug since FIND is based on EQUAL? and not SAME?:
>> b: ["one" "two" "three"]
== ["one" "two" "three"]
>> find b "two"
== ["two" "three"]
>> equal? b/2 "two"
== true
>> same? b/2 "two"
== false
JN> >> same? foo/3 3 == true
and this is a bug too since they are obviously not the same value
(I'd vote for SAME? to always return false for immutable values,
so that we can consider its semantics to be "Return true if two
values are the same value").

I agree, but the only way is to send it to feedback I think.
