Yes, "boxed" is a Java term. However, the programming pattern of using
dynamic memory and pointers is ubiquitous and ancient:
FILE *f = fopen("xyz", "r");
where f holds a pointer, fopen() returns a pointer, and "xyz" and "r"
evaluate to pointer values.
In Python, every expression evaluates to a pointer and every variable
holds a pointer.
