Error: variable `wk_Idx` is shadowing variable

Why is this usage wrong?
Or use the `each` template which is almost the same as `foreach`
to avoid the shadowing variable issue.
```d
import std.algorithm, std.range, std.stdio;
enum len = 10;
void main()
{
int[len] IntArr, i, n;
len.iota.each!((i, n) => IntArr[i] = n);
IntArr.writeln; // [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
assert(IntArr == len.iota.array);
}
```
