How many times does the following loop print? I ran into this twice doing the AoC exercises. It would be nice if it Just Worked.

```
import std.stdio;

int main()
{
  char[] something = ['a', 'b', 'c'];

  for (auto i = -1; i < something.length; ++i)
        writeln("less than");

  return 0;
}
```

Try this:
```
import std.stdio;

int ilength(T)(in T[] a)
{
        assert(a.length<=int.max);
        return cast(int)a.length;
}

int main()
{
        char[] something = ['a', 'b', 'c'];

        for (auto i = -1; i < something.ilength; ++i)
                writeln("less than");

        return 0;
}
