Right, I was just trying to point out that restricting a repeating pattern to the last variable does not satisfy an important use case, in which a *group* of variables repeats: weighted_centroid(x1, y1, n1, x2, y2, n2, x3, y3, n3 ..., xn, yn, nn, -1, -1, -1); where x,y positions are double and counts are int, and all three repeat as a group until the end marker is found. My throw-away dealt with that using a quick mod, so that I could prove to myself that our particular needs could, in principle, be met without much processing overhead (we can call our varargs routine thousands of times over a 2D image). If I interpret our combined comments correctly, it's that we need a *familiar* way to specify repeat groups, e.g., pseudo-regexp syntax, even if full regexp will not be implemented. -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
