In ruby all objects can be frozen (freeze is a method on Object, from
which all other objects derive), not just Arrays (Arrays == lists in
python; ruby has no built-in container equiv. to tuple). But that's
more of an implementation detail rather than anthing to do with the
structure/semantics of a certain type of object (e.g., a String can be
frozen, a Hash can be frozen, &c).
