Here's what I got from reading. I saw this concept of "trait" from PHP (didn't even know it existed until now) and I think it would look like this in Pascal. From what I gather the "trait" is new kind of object that merely is injected into an object but it can't itself be allocated or assigned. Does that sound like what you had in mind? program mixin; type TBrain = trait procedure Eat; procedure Fight; end; type TPhysics = trait x, y, z: float; procedure Apply; end; type TBase = class use TPhysics, TRendering, TBrain; end; begin end.
