You can already do it with a slight change, and it's not so painful, at
least in simple functions:

int foo(bool b) {
   auto result = 2;
   scope(exit) writeln(result);
   if (b) {
     result = 1;
   }
   return result;

auto ref logCall(alias f, Args...)(auto ref Args args) {
   auto ref printResult(T)(auto ref T t)

      writeln(t);
      return t;
   }
   return printResult(f(args))

logCall!foo(true);
