You are rightly assuming that the loop counter is available for all 
container types. Unfortunately, it is the case only for arrays.

Luckily, it is very easy to achieve it with std.algorithm.enumerate:

import std.stdio;
import std.container;
import std.range;

void pr(Array!int a) {
     foreach(i, v; a[].enumerate) {
         writeln("%4s: %s\n", i, v);
     }
}

void main()
{
     auto a = Array!int();
     pr(a);
}
