pair: immutable; object
-With the exception of bytes literals, these all correspond to immutable data
-types, and hence the object's identity is less important than its value.
-Multiple evaluations of literals with the same value (either the same occurrence
-in the program text or a different occurrence) may obtain the same object or a
-different object with the same value.
