Automatic Foreach

[Janice Caron]

Something at the back of my mind tells me that, once upon a time,
Walter may have planned something like that for D, whereby

    a[] = n;
    a[] = b[];
    a[] = b[] + c[];
    a[] = f(b[]);

would mean

    foreach(ref e;a) e = n;
    foreach(i,ref e;a) e = b[i];
    foreach(i,ref e;a) e = b[i] + c[i];
    foreach(i,ref e;a) e = f(b[i]);

respectively. But if so, the plan got dropped a long time ago, and now
only the first two cases work.

(Disclaimer: I may have got that completely wrong).

I don't see the problem with the foreach version though. It's
certainly transparent.
