suggested change to foreach index

[Sean Kelly]

What's weird to me is if I do this:

     void main()
     {
         int    i;
         char[] arr = "abc def";

         foreach( i, c; arr )
         {
             printf( "%i\n", i );
             if(' ' == c)
                 break;
         }
         printf( "\n%i\n", i );
     }

Then the output is:

     0
     1
     2
     3

     0

So the code compiles without a type for i in the foreach, but rather 
than use the instance of i in the surrounding scope a local value is 
used instead.  The spec isn't clear on what should happen here, but I 
would have guessed that the final value displayed would be 3, not 0.
