* [[Curl (programming language)|Curl]]: Abstract classes as mixins permit method implementations and thus constitute traits by another name.{{citation needed|date=January 2016}}

* [[D (programming language)|D]]: Since version 2.003, the __traits language extension<ref>{{cite web | url=http://dlang.org/traits.html | title=Traits | website=The D Language Reference | publisher=Digital Mars | access-date=January 23, 2016}}</ref> and std.traits module<ref>{{cite web | url=http://dlang.org/phobos/std_traits.html | title=std.traits | website=The D Language — Library Reference | publisher=Digital Mars | access-date=January 23, 2016}}</ref> helper templates provide compile-time traits. Together with other language features (notably templates and mixins), they allow flexible automatic generation of methods based on interfaces and types. D also allows explicit aliasing of member methods and variables, including forwarding to multiple member classes.<ref>{{cite web | url=http://dlang.org/class.html#AliasThis | title=Classes | website=The D Language Reference | publisher=Digital Mars | access-date=January 23, 2016}}</ref> fun fact I was told all this info
