Try with 'equal? instead of 'same? :
>> equal? a read/binary %callmov.r
== true
'same? will return 'true only if the two arguments refer (or point) to the
same memory space.
Basically, 'same? applied on immutable values should work as you expected.
For example with an integer! (immutable):
>> a: 5
== 5
>> b: a
== 5
>> same? a b
== true
>> c: 5
== 5
>> same? a c
== true ; true !
>> equal? a c
== true
but, with a string! (mutable):
>> a: "foo"
== "foo"
>> b: a
== "foo"
>> same? a b
== true
>> c: "foo"
== "foo"
>> same? a c
== false ; false !
>> equal? a c
== true

Sure, it's a good way. You can also use 'join (should be a little bit faster).
