Surrounded

Groups objects into contexts where they gain role-specific behaviors only when needed, as shown in the Employment example where employee and boss methods are isolated to the context.

Supports modules, SimpleDelegator wrappers, or interface objects for applying behaviors, allowing developers to choose the best fit, detailed in the 'Managing Roles' section.

Provides a DSL for defining triggers that automatically handle context access, with features like forward_trigger and protect_triggers for controlled execution and permission-based logic.

Enforces Tell, Don't Ask principles by making triggers return the context object, promoting better encapsulation and reducing state leakage, as explained in the 'Restricting return values' section.
