DESCRIPTION

Data::Object::Role::Immutable provides a mechanism for making any object derived from a Data::Object based class immutable. An immutable object is an object whose state cannot be modified after it is created; Immutable objects are often useful because they are inherently thread-safe, easier to reason about, and offer higher security than mutable objects.
