Especially when for loops can be infinitely long. :) I think the actual 
syntax of 'for' may be surprising to most:

   http://dlang.org/statement.html#ForStatement

import std.stdio;

void main()
{
     for ( {
             int i = 0;
             double d = 0.5;

             struct S
             {
                 string s;
             }

             auto s = S("hello");

             writeln("I am in the initialization clause of a for loop!");
         } i < 10; ++i) {

         writeln("i: ", i, ", d: ", d);
         d /= s.s.length;
     }
}
