In the sense of supporting mixins that don't necessarily pollute your public API. The overlap with other languages isn't perfect, and traits in the stdlib refer to a rather different template-based thing, but I don't think any language has the monopoly on a canon definition of traits. Certainly they're going to be different than traits in Self, which iirc coined the term.
