    {
      int i;
      for (i = 0; i != N; ++i) /* nothing */ ;
    }

"is localized" and "will not pollute the other namespaces".
I suppose that by now all current compilers get the duration of i in
     for (int i = 0; i != N; ++i) /* nothing */ ;
right, but it wasn't always so.  And it is not the same as in the block 
version.

Well, you recall incorrectly.

If you depend on something that isn't true, it's _not_ a good thing.
