Line 1: '''Trait''' is an [[abstract type]], used as a "simple conceptual model for structuring [[object oriented]] programs."[http://web.cecs.pdx.edu/~black/publications/TR_CSE_02-012.pdf]. Traits are similar to [[mixin]]s, but may include definitions for class methods. Traits have been proposed for inclusion in [[Smalltalk]], [[ActionScript\|ActionScript 3.0]] and [[PHP]], and are found in Moose ([[Perl]] 5), [[Perl 6]], and [[Scala programming language\|Scala]]. There's also a Traits module for [[Python (programming language)\|Python]] [http://code.enthought.com/projects/traits/]. ''Module mixins'' in [[Ruby (programming language)\|Ruby]] are similar to traits to some degree. Traits were initially developed at the Software Composition Group, [[University of Berne]]. == External links == * [http://www.iam.unibe.ch/~scg/Research/Traits/ Traits] * [http://citeseer.ist.psu.edu/566972.html Traits: Composable Units of Behavior]
