Yeah, the loop counter is automatic only for slices. You can
use 'enumerate' for other types:
foreach (i, element; NumberRange(42, 47).enumerate) {
// ...
}
That is taken from the same page: ;)

if my opApply() is defiend as the following:
int opApply(int delegate(ref int, ref T) del)
{
int result;
foreach(int i, T val; _app.data)
{
result = del(i, _app.data[i]);
if(result)
break;
}
return result;
}
and called like:
foreach(int i, MyType p; places) {
isn't i the loop counter?
