What you need is a range that produces void * instead element itself.
This would probably work:
struct VoidRange
{
void[] arr;
auto front() { return arr.ptr; }
void popFront() { arr.popFront; }
bool empty() { return arr.empty; }
}
foreach(p; VoidRange(b)) writeln(p);

Yes... I could do this... but then, I would construct millions of
structs to hold just ordinal numbers... Using a iota would also be a
possibility... but I want something even less perceptible...
Hey, there's nothing wrong with for-loops. Just trying to answer the
question :)
You could also do something like:
foreach(i; 0 .. b.length) writeln(&b[i]);
