Implementation of Traits in Perl
Traits are a simple composition mechanism for structuring object-oriented programs. A Trait is essentially a parameterized set of methods, which serves as a building block for classes and is the primitive unit of code reuse. Unlike mixins and multiple inheritance, Traits do not use inheritance as the composition operator. Instead, Trait composition is based on a set of operators that are complementary to single inheritance and result in better composition properties.
Traits are a core part of Perl 6 (called Roles there), and Class::Trait implements traits for Perl 5.
