Ah, I see. I missed that part. Is the on-demand nature of conflict detection (for traits built with Object.create) somehow unavoidable, or was that simply a design choice? > function Point(x, y) { > this.x = x; > this.y = y; > } > Point.prototype = Object.create( > SuperPoint.prototype, > Trait.compose(.....)); > > Is that the kind of usage you had in mind? Yes, exactly. Sorry for my oversight. Dave
