You might be able to make it a function:


bool foo()
{
     auto fn(A)()
     {
         A delegate(A) fn;
         fn = delegate A(A a)
         {
             return fn(a);
         };
         return fn;
     }

     return fn!(bool)()(true);
}

I don't really understand your need though, can you post more 
context?
