Had an idea how to make more nice trusted blocks:

import std.stdio;

T trusted (T)(T delegate() @system dg) @trusted {
    return dg();

void main() @safe
     writeln("Hello D");

         writeln("C ", cast(void*) 1);

looks a lot better than anonymous functions that are called right 
away after being defined.

Best regards,
