Haxe has a similar (but not quite identical) bag of tricks which act as a "gradient" of stronger/weaker couplings. You have to specify that an implementation can use a specific interface, but you may overload an implementation with multiple interfaces. http://haxe.org/manual/2_types#interfaces http://haxe.org/manual/2_types#interfaces You can use structure types instead of classes and rely on structural subtyping to match them. http://haxe.org/manual/2_types#structural-subtyping http://haxe.org/manual/2_types#structural-subtyping And you can ask for dynamic type behavior wherever the code needs it. http://haxe.org/ref/dynamic http://haxe.org/ref/dynamic
