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;
    }
}

I love this feature so much ^^
