(A silly workaround is the following, but I do not know if this has been 
documented since it has been discovered:


     void func(T)(T data) {
         void subfunc1()() {
             process(data);
             if (recurse) subfunc2(); // Ok.
         }

         void subfunc2() {
             process(data);
             if (recurse) subfunc1(); // Ok.
         }

         subfunc1();
     }
)
