The current value space contains booleans, exact and inexact numbers, characters, symbols, strings, the empty list, pairs, vectors, bytevectors, procedures, and escape continuations.

(list (vector? #(1 2)) (bytevector? #u8(1 2)) (pair? (cons 1 2)))Result
OUTPUT
(#t #t #t)Current guarantees
- Pairs, strings, and bytevectors are immutable in the current profile; vectors and lexical cells are mutable.
- Quoted aggregate data is immutable; constructors create runtime aggregates with the documented identity rules.
- Improper and cyclic structures are distinguished from proper lists; deep equality terminates on cycles.
Boundaries
- Complex numbers, ports, records, and mutable pairs or strings are outside the current profile.
- Internal outcomes, signals, and uninitialized sentinels are not guest values.
