I don't think it's productive to compare the behavior to C. C is 
now 50 years old. One would hope that D has learned a few things 
in that time.

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;
}
```
