The trailing closure is beautiful!

I've read a bit the Swift documentation and it seems that it 
works well for them because of how APIs are modeled, i.e optional 
trailing delegate is idomatic in their libraries.

Let's compare to D.
1. lambda are often used as template parameter.
2. non templatized lambda are often lazy, i.e build by the 
compiler from an expression.

   void get(lazy string) { }

   void main(string[] args)
   {
     get() {return "a";}; // would not work, similarly to 
"get({"a"})" that does not.
   }

Not sure if that would work well.
